How expensive is it to print shit all day? Not worried much about power but the filimant for random shit. Mostly will be just desctop crap but i want to build gears for kids power wheels and shit. And if i could get thethem durrable enough to use for other projects it would be cool. I just dont want to buy an ender 3 and then let it rot because filament is to expensive.
>>
>>1532095
>How expensive is it to print shit all day?
Ultimaker 2 can print 24mm3/s with the right nozzle, which is about 0.03 grams per second, or about 1.8 gram per minute. A 750g spool of filament at maximum flow rate will last you about 7 hours at that rate, but that's really the upper end of what most machines will do.

Practically speaking, you can use about a spool of filament every day on a machine, which is between 10 and 50 EUR depending on material and quality, 20 EUR is about average (if not above average).

However, it's up to you how much you use, and how many days per week you'll be printing. I find that I'm designing more than actual printing, but that's the other way if you're just starting out. For a bit more scope: on our uni the average consumption rate is about 2 rolls of filament for a projectgroup. A typical project lasts about 10 weeks, and includes a team of 6-10 people, so that's way less than a roll per week. It becomes a lot more when you're a dedicated designer though, with direct access to a printer.
>>
>>1532102
I see. Well thank you anon. I think i can swing that after Valentine's day. Hope to have a shop full printing away but I'll start small and learn the machine. Assuming what we make takes off it shoukd be a fast and cheap crash course to becoming at least ameture teir with a printer and fusion 360.

I don't understand the Caitlyn hate, She doesn't look that awful considering her age and I don't think she was doing it for attention because if you look at old footage the feminisation has been going on since the 80s.

Printing gears is problematic, printer tolerance is generally bad, ABS may warp even and you have to watch the gear RPM and torque because 3D printed parts can't take a lot of stress. I wouldn't say it's not doable though, you just have to be careful with your design and finishing, it's not a case of print and go.

How do i set a priming line in slic3r?

I added this to the Start G-code textbox:
G1 Z0.2 F3000 ; lift Z
G92 E0 ;reset extrusion
G1 Y120 E10 F600 ; prime
G1 Y150 F5000 ;wipe

When i start the print, the printer executes the above lines before M109 S... so it tries to cold extrude. Is it possible to add lines after M109 S...?
>>
>>1532250
just add M109 S[first_layer_temperature] before your priming line in your start gcode

For the ender 3 owners out there, you might have noticed Cura can't connect to your ender 3. The devs are retarded and it's a bug in their usbprinting.py plugin and they won't fix it because "third party printer lol". You can search this and fix it yourself, or you can also use another program called printrun which is available from any relevant Linux repo or online for Windows users. It has one feature that I've never found anywhere else: area exclusion mid print. If you're making a chain and printing 10 links and 1 of them shits itself, you can pause the print, tell it to not print in that x-y range the link is on and resume the print to save 9 links and save filament. That alone makes it worth trying. I couldn't get it to do any slicing on its own so I just use Cura for that. Here's an example workflow that I use.
>Cura: save gcode
>printrun: import gcode

It's not quite as refined as octopi, but connecting direct to a PC has perks that an RPI can't offer.

I did that at first and then the RPI died on me. No clue how. It booted once and then after the reboot nothing. Luckily Amazon's replacement policy lets me try the replacement and the old one side by side - that's the only way to check if the Pi3 B+ is defective or not.

Just flash a different SD with a fresh os and see if it boots. If not wipe the bootloader and try again.
If that fails you know the RPi is dead.

Not quite. They have been shitting themselves at random thanks to the GPIO pins, and the official documentation says for the 3 B+ the only surefire way to check is to try booting a known good one side by side with your "bad" one to see if it works.
So that's what I'm gonna do.

When you guys do the "paper method" to level your heat bed, do you get it just at the height the paper won't slide under the nozzle anymore, or do you lower the nozzle until it touches the paper an then pull it out an move the nozzle and repeat?
For me, leveling the bed is taking a long time I'm still on the first corner I started on, I tried moving to another corner but my nozzle was touching the glass, when I corrected, the other corner was fucked up again.

Last thread I asked about calipers but I couldn't follow up with the replies.
I forgot to say that I need the pieces I would be printing to fit as precisely as possible because I'm making pieces to modify an action figure so I'm looking to be as precise as possible with my measurements.

Is my best choice the digital or the vernier calipers? I can find both for about the same price.
>>
>>1532982
You'll get the same precision with both if you're buying shitty ones. I'd recommend against cheap digital ones because they eat batteries when they're not in use, and you'll be constantly picking up a pair only to find it dead. If you can read a vernier then go with them, but also look into dial calipers as they're nicer to read.

Instead of having woodwork I had art class and "tutoring" in my country. You are quite literally banned from learning anything useful before finishing high school.

>>
>>1533009
That's the vernier. What you do is clamp something in the calipers, and read the big scale. 0 on the little scale marks where you should read. If it isn't perfectly on one of the big lines, you'll want to look at the number to the left. So if you're in between 4 and 5, you read 4. What you do next is read the vernier. This tells you with 0.02mm accuracy (usually). How you do it is simple. See how most of the small lines don't align with the lines on the big scale? Look for the line on the small scale that aligns best with any line on the big scale. This is your precise measurement. Easy peasy, but much better demonstrated with a gif.
So, let's look at the picture. We start by reading the big scale. Left of the 0 mark is 28mm. We now read the vernier scale. The best alignment is at 6, right? That means our measurement here is 28.6mm.
It isn't as exact as a digital caliper, but it's good enough 99% of the time and it'll never run out of batteries. Usually cheaper too.
>>
>>1533020
>It isn't as exact as a digital caliper,
it's just as exact as a digital caliper with one decimal place.
>>
>>1533022
I've never seen one with so few decimals, but you're still a bit wrong. Almost all verniers have +/- 0.02mm accuracy, as the vernier scale is usually only graduated into fifty steps. Each line on the vernier scale represents 0.02mm, whereas a digital caliper with two decimals would show .01.
Like I said though 99% of the time they're good enough, and it's not like Chinese digital calipers are that well calibrated anyway. Learning to read a vernier is very easy, and reading it is quick. I've been measuring stuff for two decades and never felt a need for a digital one.
>>1533019
I'm sorry to hear that. My school taught art one year as a mandatory, and then two years as an elective between art and music. We also got a "crafts" elective, which was a choice between wood+metalshop and sowing, four years of crafts in total. We then had high school electives, where you could choose stuff like computer science, or childcare, or carpentry, economics and science, bunch of other stuff including car mechanics, sort of like a mini-college. Then there was real college.

Wood+metalshop was the best though. I made a morakniv, a sort of craftsman's knife, with a bone and leather wrap handle that I still use today, also a composite bow and and steel arrowheads, though blunted, and a riveted viking helmet. I know kids today aren't allowed to make knives and bows, but they still do have crafts. They make stuff like shelves and key cabinets nowadays.

Anyway, just buy a cheap vernier caliper. It'll be good enough, your 3D printer won't print accurately enough for 0.02mm to matter and you'll be filling your part for a perfect fit anyway.

Stop telling people you can repeably measure more exact than 0.2mm with a caliper. (analog or digital)
Yes it shows higher resolution,
Yes it is advertised like this,
no this precision is not given due to the overall measurment concept of a caliper.
http://m.cmm-nano.com/info/the-abbe-principle-nano-metrology-19327204.html

When you're talking 0.02 (!!), the amount of heat from your hand will set the measurment off.
Ever wondered why micrometers have a plastic guard as a handle? To keep it from warming up by your hand.
Micrometers reach to about 0.02 and they have to be calibrated with nominal gauges to the given temperature and humidity.

Anything more precise than that can only be achieved with a CMM in a climated environment using statistical methods. (eg. determining a diameter with gauss-deviation, outscribed circle, inscribed circle, center of area-mass of the given contour or whatever you are looking for)

(skilled industrial mechanic and quality engineer in automotive)
>>
>>1533202
Does that mean carbon fiber calipers are actually better than steel calipers?
>>
>>1533202
So are you saying that a measurement taken by a caliper is only accurate +/- 0.1 mm despite the impression given by the vernier? That's pretty interesting.
>>
>>1533202
A quality set of calipers is good for about .002" (.051mm)
Cheaper ones can be trusted to about .005" (.013mm)
(refurbished cutting tools with a tolerance of .0002" sometimes, and built industrial machines)
>>
>>1533215
>.005" (.013mm)
*(0.13mm)
>>
>>1533213
Even 0.1mm is veeery optimistic for a caliper. Only a high quality, well adjusted one could reach 0.1mm.
Classical vernier sane resolution is considered to be 0.1. Mine goes to 0.05 but this precision is imaginary due to other circumstances during measurment.

>>1533215
What are you even talking about?
>A quality set of calipers is good for about .051mm
>Cheaper ones can be trusted to about .013mm
Your cheap example is 5x more precise than your expensive one

Where do you get your wisdom from? Ever looked into measurment theory?
Why do other measurment instruments (like much more expensive micrometers) even exist when calipers are as precise as you claim them to be?

Printing gears with nylon works great, just use at most a .25mm nozzle for small gears, nylon filament, that you bake before you print, and a PVA bed adhesive, gluesticks FTW.

For even better gears remember to increase your number of perimeters to 4 or greater, then grease them up when installed.

It's not fukken hard. Most RC gears are some variety of glass or fiber reinforced nylon anyways. And those are the high end shit. Most average stuff is nylon.

PS if you're a poorfag just go to the bigbox store and buy some round weed-wacker line. Make sure it is approximately the same size as your filament 1/16 ~=1.75, bake that shit then print with it.

How do I level the printbed? Anycubic i3Mega. Is it literally just put the extruder as low as possible and turn the knobs until a one piece of paper can fit between? If so then I have done it right,.

I pre-heat the nozzle before I start. Any leftover filament on the end of the nozzle will throw off leveling by a great deal, but if it's melted first it just comes off on the paper.

200, the usual melting temperature. If I'm cleaning the nozzle, I'll put it to 90 or 100. Warm enough to make it soft and sticky and easy to remove. Do that first. Get the nozzle nice and clean, relatively speaking. Then up the temp and set your clearance. If there's one thing that ensures a successful print more than anything else, it's getting the base set right.

Please help! My Bowden tube got clogged and the PLA being broken from whee it feeds into tube is culprit! I was doing my first ever print and I paused and then when I resumed later, it never extruded again. Removing the Bowden tube on the feeder (not nozzle) end revealed that the PLA was snapped just beyond the feed, which explained why no line would feed beyond the Gear insert thing.
I cannot pull the PLA out but I haven’t removed the nozzle end of the tube yet either.

I changed the CR-10 default firmware to marlin1.1.8.
When a print finishes, the printer turns off the heaters as expected.
But when i turn the extruder heater back on (to start up a new print), the controller starts to heat the nozzle for a couple seconds and then stops with an error:
Error:Heating failed, system stopped! Heater_ID: 0
Error:Printer halted. kill() called!
Only resetting the printer will let me do anything after...

But it clearly heats the extruder as you can see on the pic. Is there a setting in marlin to fix this?
>>
>>1534061
Is the nozzle clogged?
It sounds like you let the filament stay in the nozzle while it was cooling down, if you're going to pause a print you're almost always better off to either not or take the filament out of the extruder
>>
>>1534115
I am printing with the nozzle right now, it is not clogged.

If i let the nozzle cool down to 50C or so and then turn it back on this error doesnt happen and it will just start a print normally. The problem is when i start a new print too quick and the nozzle is still hot.

Might be a janky thermistor, this is the thermal runaway protection that was probably disabled in the stock firmware. You might want to fiddle with this section:

They run on the same business model as inkjet printers, they use proprietary filament that they overcharge for, the models have like a 3 year sale life before they're considered obsolete, and each model has it's own specific filament you have to buy just for that model, and theres no 3rd party support, IIRC doing any maintenance yourself, including printing an upgrade peice completely voids your warranty, and you have to use their proprietary slicer software
They arent bad for obsessive parents trying to get their kid into super nerdy smart guy type shit early on so they can get into a "good" college, but are arguably the worst printers on the market for proper hobbyists
>>
>>1534139
Pretty much what >>1534145 said
Just heat your head up to temp, and force your machine to extrude until it comes out
If it doesnt you can try to stack your nozzle in acetone to weaken the plastic and then take a brass brush to it, I've never had to try that but I've read it works if you can't get a replacement nozzle
>>
>>1534119
Replied to the wrong person lol
>>
>>1534183
They stopped doing all of this for their pro model at least, you can use 3rd party filament and slicer now. Still if you are a complete noob like I was you wouldn't care about any of this. The Junior models still probably only take proprietary filament but they're for fucking kids.
Kek mine did last exactly 3 years, bought it in 2015, it died in 2018.
If they hadn't ditched that HP-tier business model yes I would have chosen another printer but they have and I am used to using DaVincis and I really just want to get an overdue project finished. Don't have time to learn and tinker with a Chinese brand. The ONLY reason why I considered the Creality is because of it's 500mm build volume but

$188k in revenue last year, $85k after expenses.
expecting to get completely raped in taxes in a few months so $50k will probably end up being my actual profit for the tax year. That will change in this coming year as I'm going to start seeing residuals and royalties from licensing deals.

> I hope this is not just another word of mouth/connections thing that got big.
I've been in the hobby over 10 years so my name has some weight to it from that. But my product is serving a largely ignored niche within the hobby. I'm also offering features and performance that the few that I do compete with don't or can't offer.
>>1534304
>is there a particular niche left to fill
There are different power sources for shooting darts. The already widely-served area is in batter-powered flywheel blasters. Everybody is producing those.

Spring-plunger designs were being neglected and those are what I was most familiar with already so that's what I'm selling.

The most neglected segment are the low-pressure compressed air blasters. These were pretty commonly sold commercially until a few years ago and this segment of the hobby is almost completely dead. There's a niche for you.
>or would any competition cut into your margins?
I have 4 to 5 week lead times on blaster orders because I'm doing everything myself with no employees. There are a few other individuals in the hobby producing and selling these, but they do require more tools and time to make than most people are willing to invest in. So nobody has tried to produce them in anywhere near the same quantity as me. I'm also offering way more customization than they are because it's my design and changing it is easy for me.

The licensing deals underway already are going to present some competition, but those won't be as customized because they're be in much larger production quantity. And most of those sales will be in countries where I'm not able to sell as many because the shipping and customs issues price me out of those markets for the most part anyways.
>>1534307
They're PLA except for the coupler.
>>
>>1534312
>You may as well start injection moulding the parts at this point
I don't have tens of thousands of open orders. Nor do I have a small business loan that would be able to pay for $40k in mold machining.

And say I did. Now I need a warehouse to store all the part shipments and a ton of employees I also don't have money for. Financial risk is a staircase that you walk up slowly and carefully. I'm not even really interested in growing my business any faster than I already have.

Even the large company that I licensed the design to is going to be producing them via printing. Because they don't want to take such a huge financial risk on a market segment they don't know the long-term demand of. My sales volume has been quadruple what I anticipated when I made the first dozen or so. But even then it's not like I'm swimming in a vault full of cash yet.
>>

>nerf kids
Most of the spenders in the hobby are over the age of 20. Frankly children (or rather their parents) make the worst customers imaginable because they don't know a damn thing about the product they're spending money on, and that leads them to having unreasonable expectations.

>>
>>1534366
>Is it dead because no one uses that style anymore or is it dead because the 3rd party support switched their tooling because the retail market was saturated?
It's dead because I would assume the manufactured ones had a high rate of returns/leaks. That and the flywheel blasters are probably much cheaper to manufacture.

On the hobby side they're only neglected because There's always been very few people developing them. Making low-pressure valves that work involves a fair amount of engineering and machining. I tinkered with them before I had any familiarity with 3d printing.
>>
>>1534148
Thanks for your advice.
I discovered the issue because the gear that feeds my filament stopped doing so, I can’t “push the filament through” or pull it out of the tube, and as a result it won’t feed into the already full fed tube. So far Ive made no progress removing it and getting my feeder to feed with the spin of the gear. When I attempt to remove the nozzle end of the Bowden tube, so far I can’t wiyhout fear of breaking the mechanism. Can I heat the nozzle and manually push the filament into it and it moltens at one end? Should I just unscrew the nozzle assembly?
>>
>>1534307
>The 1.0 Pro. It's red and black.

Ok, that model appears to be actually decent, unlike everything else they've come out with. It's *almost* like a normal printer, with some "buts":
- You can load any filament (but no normal spool will fit in the small cartridge bay)
- You can use any slicer (but the gcode has to go through their proprietary XYZware)
- It has auto bed levelling (but it's not real bed levelling, more of a step-by-step wizard for the old "paper method")

At 300$ you're getting more or less the same features as an Ender 3, but with an enclosed build volume, (i assume) a rigid motion platform, but also a locked-down firmware.

How did you make it purge? Is there an option. I tried doing a print to do this, but I can’t get it to feed since the tube is blocked by the broken filament inside it, and that filament doesn’t want to move in any direction.

These shoot 100 to 120 feet depending on which of the four springs you install, the barrel length, and which of the two ramrods you use. So you can dial it up or down depending on how/where you want to use it.

I need your help, /diy. I have access to clay printer at my uni, printed and fired few test pieces recently. Now I want to print simple mug, but I need help with slicer settings to print pic related mug (fig 1). To achieve best surface, I need to use Vase mode in Cura, so nozzle is giving continuous clay noodle. Models must be solid to be sliced right in vase mode (fig 2), but I cant set up Cura to print shut mug`s bottom without printing bottom of handle piece (fig 3). How can I do this? Is there some g-code editors in which i can simply select handlepiece`s bottom layers and delite it?

A workaround might be to Print the bottom in regular mode and add the rest in vase mode. Either manually or with some manual g-code edditing.

Hey guys long term /diy/ poster, but first time in this general.
Have recently purchased a 3D printer and am messing about with it. It seems to have decent performance out of the box, and I was astonished by the quality of the first print. I am printing an enclosure for an electronics project now, however I have run into some issues.
(Yes I have read the simplify3d support, it doesn't mention anything about this problem)

My printer seems to have relatively bad performance in bridging, namely a very thin stringy bridging (see the picture). I think this could probably be improved, but I was wondering if people have already had this problem and know a way to solve it. I tried messing a bit with printing speed (80% and 60%) and extrusion rates (up 10%) but none seemed to really have any impact.

I would prefer to fix this before printing the actual enclosure (what you see here is the lid) because it has more critical parts where bridging is important.

>Make & Model
Creality CR-10
>Filament type
PLA that comes with the printer
>Bed & Extruder temps
60 degr, 200 degr
>Print speed
100%, i think that is 600mm/s in Cura
>Extra info
3D software: solidworks
Slicer: Cura
In Cura I selected 30% infill with 0.2mm layer height, build plate adhesion with for the rest 'recommended' settings for the CR10.

Note that on the left side of the picture, that is support material thus irrelevant. What is mostly interesting is the fill that is going on top (that it is so thin) and the stuff marked in green.

Thanks in advance, since I am kind of at a loss.

Increase the cooling fan speed, the extruded material needs to cool as rapidly as possible for bridging to work right. Also calibrate your extruder, that brim looks underextruded to me - the individual lines aren't supposed to have gaps between them. Look for the ol' Triffid's guide
>>
>>1534893
>Increase the cooling fan speed
Cooling fan is already at 100% by default (except for the first layer, which I am pretty sure is to make sure it binds well with the bed)
>Also calibrate your extruder, that brim looks underextruded to me - the individual lines aren't supposed to have gaps between them. Look for the ol' Triffid's guide
Yes I was thinking it was underextruding as well. I wasn't aware of the guide, I will try that. Thanks a lot!

What happens when your filament dries out?
I finally got my printer put back together after about 2 months of down time, and now it wont extrude
The hot end is hot and the Bowden will push the filament but it wont melt and come through the nozzle

SW armour anon here. Ive been slacking the last month but now decided to continue. Problem is, my printer is limited to 200x200x200mm and that simply doesnt cut it for big pieces like chest armour. So what printers are out there with bigger printbeds with reasonable prices?
>>
>>1535102
how long did you leave it unsealed? i know about filament taking up water and spitting out bubbly stuff on the other end but completely dried up?
>>
>>1535114
Its been sitting in a desk drawer since I took the printer apart, so about 2 months of exposure since I bought the roll
I cant think of any other reason it wont extrude, theres no clogs or bends in the hotend
>>
>>1535116
you sure about the no clogs? that stuff wont dry out that fast. have you tried a different roll of filament? have you checked just the nozzle itself, thats the part on my printer that usually acts up every month or so and forces me to disassamble and dunk it in acetone
>>
>>1535122
I haven't taken the whole block off to check the heatsink, but the 0.4 nozzle was clear and the brand new 0.5 i put on was clear
I only have the one roll right now
>>
>>1535132
well, then look at it from this perspective. if your filament is indeed unusable now, you have to buy new one anyway. and if the new one still doesnt work, you know the old filament was fine and the problem lies somewhere else

Better cooling + Increased horizontal & vertical separation (proportionate to layer height with some slicers) and supports just pop off. Tweaking and tuning is key.

So my Ender 3 came in yesterday and I put it together last night. I noticed that the rollers on the bed felt like there were flat spots on them when manually moving it but after running my finger across them I didn't feel anything. I googled the issue and found a reddit thread suggesting to loosen the rollers. This helped but im having trouble adjusting it to make it completely smooth and not have any wobble. Is there any trick to adjusting this?

Also are there any other things I should check before trying my first print?
>>
>>1535371

Is there any ‘good’ to using springs under my print bed (requires constantly releveling) or can a double washer lock going to allow me to avoid recalibration?
New to printing, I’ve been using PLA pretty well, but I think I’ve got “salmon skin.” My PETG is almost imposssible to make stick and even when it does, it un sticks mid print (the whole print). I’ve followed PETG guides and they vary wildly (some say 245 degrees c some say 210). I hear my ceramic/glass bed to 70c-90c on these attempts, but I can’t finish one single print in pet g.
Any ideas? I’ve tried masking tape (worked for a while till whole print suddenly unstuck), hairspray, a combination of these, and at one pint I tried taping my print down mid print to force it in place. I want to use petg but it seems like a very difficult filiment to get working, any advice?
>>
>>1535379
What if I don't need to pay import fees? That's 245 euros per printer worth of possible profit.
>>
>>1535389
For reference this is petg starting. It always does a random line and I always have to catch it because it sticks to nozzle, if I succeed pulling the initial stick filament off, it gets a little farther than this before the main print spontaneously stops sticking.
>>
>>1535371
>If you use the correct warehouse in Aliexpres don't pay any import fees in the Schengen zone.

Good supports are a balance between printing temp and perfect bed leveling. However, no support material is always going to be 100% perfect, so it's best practice to avoid needing them at all, or using as little as possible.

Filament NEEDS to be dry in order to print. Moisture in the filament causes tons of problems. It sounds like your temps are way too low or your nozzle is plugged. You can buy super tiny drill bits to help clean your nozzle for cheap. I usually just use a strand of wire though.

>>1535111

Unless the bottle says "pure acetone" then it's not acetone, which is what you need. Acetone also is used as a paint thinner, which you can buy for way cheaper than "nail polish remover".

Good job anon, post some prints now
>>1535389
Make sure your nozzle is close enough to your bed using the paper test. And try using a glue stick, adding three layers in different directions for each application (let the glue dry between applications). It's what I use on my heated glass bed and I've never had issues with adhesion.

>>
>>1535451
>It's cheaper than the Ender 3

Because it's a fucking mess of exposed wires and made out of plastic. The ender 3 is in a completely different class.
>>
>>1535451
The Anet is the quintessential chinkshit prusa clone. That means it's basically a well-packaged printer kit that you have to assemble and tune yourself. The Ender 3 is marginally more expensive, but has a few years more development behind it and comes int wo segments that bolt together and should work right out of the box (emphasis on should).
Both are equally good value: the Anet is a good learning experience, the Ender is undoubtably the best out-of-the-box printer at that pricepoint right now. Do you want to print tomorrow? Get the Ender. Do you want to print eventually and learn a lot? Get an Anet. Also consider the A6, which should be a bit larger iirc, and shop around for other i3 clones.

Thanks, for the advice! I don't mind the exposed wires and plastic as long as it can do a decent print, also it couldn't hurt to learn about the machine since I'm a complete beginner when it comes to 3d printing. So I think I'll go for the Anet - I'll update if it turns out to be crap

I do the opposite. I tend to build an ugly version in CAD, do a test print, then print out a paper copy of the design after I know it works. I doodle on the paper copy to try and unify the shape and design aesthetic of it, then come back to the CAD and iron away the ugliness.
>>

Just use super glue. The "wood" content of those filaments is only just enough to make them compatible with wood stain and urethane, but not enough for wood glue to actually do much.

The advantage would be the ability to solvent weld the layers. If I'm right you'd get ridiculous layer adhesion, but the spray would have to be incredibly fine and precisely controlled.

I'm trying to understand your logic here. If you work 40 hours a week (standard working hours in USA), and make $20 an hour and even it out over total hours in a week (168), then you're making on average $4.76 an hour. If you're trying to be smart and save money and have people do shit for you, then you'd need to use $4.76 as a reference. So in order for you to save money by buying a prebuilt, which costs $20.83 an hour, you would have to be making $87.48/h, not $20.83/h.

I went to the cinema once. Not only didn't I get my hourly wage during that time, no, I actually payed money for it.
How could that happen

Just doodle some shit with a pencil. You don't need to bring industrial drawing quality to the paper.
I usually do it when there are a lot of important dimensions to consider so I don't get lost.

But that's precisely the reason I cited. I just want to use my 3D printer for my projects.

I'm a mechanical engineer. I know how a fucking 3D printer works. Honestly this thing is built more like a toy compared to the machines I work with, but I'm getting it because it's cheap.

I could work overtime to afford the extra $250 more quickly than I could put it together myself.
