for modular construction of polyhedra
>>568307Half-finished snub cube (twelve 90-90-90-90-90 modules)The darker module at the lower right corner is made from genuine Post-It Notes; the others are knockoffs from Target.
>>568308Truncated triangular prism (eighteen prototype 90-135-135 modules)
>>568309Octahedron (six 90-90-90 modules)This looks uglier than it should because it's an inverted model but it was made from non-inverted modules.
>>568310Whoops, that octahedron is 90-90-90-90 modules, not 90-90-90, obviously.
>>568307that is a very nice looking piece of paper reminds me of people who write math notes quickly but have beautiful handwriting/calligraphy skills and it looks like it was prepared for hours
>>568308Same model, now completed
Rhombic dodecahedronModules: 8 135-135-135, 6 90-90-90-90Post-It Notes: 3 * 8 + 2 * 6 = 36The 135-135-135 modules were distressingly fragile during assembly, but they settled down after the model's completion.
Which one is great for a regular icoshedron?

>>569914I personally dislike Star Trek and am not very well acquainted with it, but I think a Tribble joke would be appropriate right about now.
Of course, these modules are not limited to 3-inch sticky notes. 8.5-inch paper works just as well.https://en.wikipedia.org/wiki/Gyrobifastigium
May or may not bother to finish this GIANT piece I started a while ago.
For some inspiration, I always admired the modular work of this guy:https://www.flickr.com/photos/mancinerie/

OP here. Are my modules really SO boring that nobody is interested in trying them out? :-(Photo is an octahedron folded from 4-leg square modules, but with the edges of the modules reverse-folded inward so that models with tighter vertices can be constructed. I'm not a big fan of the look, but the non-reverse-folded module can't handle the tightness of this polyhedron's angles.
>>576200I am trying them out today. Does it work with regular printing paper?I'll post results when done.
Sorry for the double post, but OP, do you have instructions as to how to combine the modules to make basic things until I get the hang of them? They definitely look interesting, and I would recommend you put them in some sort of pdf.
>>577802>Does it work with regular printing paper?Yes, as you can see in >>570160.>>577803>do you have instructions as to how to combine the modules to make basic things until I get the hang of them?I mean, it's pretty simple. Insert the tip of one module into the slot that's above the tip of a second module. The simplest model that you can make with the basic module is the cuboctahedron: https://en.wikipedia.org/wiki/Cuboctahedron>I would recommend you put them in some sort of pdfI may do that in the future.

Working on new variations on these modules.A hexagonal or pentagonal module may be useful for folding deltahedra (polyhedra composed exclusively of triangles, like >>576200 and >>577846). By a happy coincidence, the height of a hexagon is almost exactly seven-eighths of the height of a square, so folding an almost-perfect hexagon is a lot easier than you would expect. The pentagon proportions aren't quite so convenient; whether or not an approximate module would work well remains to be tested.
Pic related is a tetrahedron, made from the new hexagonal pattern shown in >>577907.(The triangular pattern actually isn't new--I just didn't have room to include it in the instructions photographed in the OP. The hexagonal pattern, however, <em>is</em> new, as I didn't realize until recently that folding an almost-correct hexagon could be almost as simple as folding a perfectly-correct triangle.)
>>568344That d is for donut(ed)
>>577907Folding guide (somewhat blurry)As a (very) rough rule of thumb for gauging the time that a model will take, you can assume that each square module or triangle module takes five minutes and each hexagon module or double square module takes ten minutes....is what I would like to say, but I keep getting "connection error", so I'll upload the photograph later.
>>577846Twelve models, ready for delivery.
>>568307this style of module production isnt new, there is an old book about these i found at the minneapolis central library that shows these and others, also thats an OG image i had these instructions saved on my phone five years ago.
>>579064I assumed that such simple modules had been invented by others. At least I can claim the honor of inventing them independently.
