@rasjor @nanma80 Geogebra has a Net tool/command, but it lacks flexibility -- I guess the dedicated could edit the source code

I needed a bpy refresher. So I made a script to generate some polyhedra that Blender apparently doesn't have (Maybe bc they are not regular). After some calculations, I made the pentagonal trapezohedron, the d10 die in RPG. #blender #polyhedra #polyhedron #nomxd #Tech-talk
Zero expansion materials have the interesting property that as they heat up, their crystal structure changes, without changing volume. #Huygens #origami (bistable) #polyhedron
Truncated ‘cuboctahedron’ mapped from continuous polynomial x^80+y^80+z^80+.6133^80((y+z)^80+(z+x)^80+(x+y)^80+(y-z)^80+(z-x)^80+(x-y)^80)+.5286^80((x+y+z)^80+(x+y-z)^80+(x-y+z)^80+(-x+y+z)^80)-1=0. An Archimedean solid, it has 26 regular faces (6 octagonal, 8 hexagonal and 12 square), 48 vertices and 72 equal edges. It is not a true truncation of the cuboctahedron which instead results in 12 rectangular faces rather than square. However, with a bit of (mathematical) stretching, the requisite all edges equal condition can be met. #Maths #Mathematics #Math #polyhedron

Perfect fit.
Fun with chiral shapes - cube from snub cubes.
I've finally managed to put my entire "geodesic series" of himmelis side by side, thanks @noira_musti for the suggestion. The edge counts are 6, 12, 30, 36, 42, 48, 84, 90, 120, and 210.
Does a polyhedron exist for the distributive property? A distributohedron? Like a associohedron and a permutohedron. #math #polyhedron
I'm very grateful for the various #TTRPG #media tips.
I really appreciate #Polyhedron for his thoughtful perspectives. Like him, in my opinion, that players can/should (!) prepare as well. GMs are not (alone) in charge of the fun! They're also "players" but with special tasks.

Polyhedron made from differently colored interlocking plastic tiles; when I was out looking for squirrels I caught this at Cornell's Mathematics Library in Malott Hall

Next project, a Tetragonal Deltohedron LED polyhedron.
It seems If you are making Art PCBs eventually you make the LED Cube style project.

Here's a great video by #Polyhedron on YouTube about why #Ironsworn, one of my favorite games, and other games like it will make you better at DnD.
Semi regular polyhedron morphing
The polyhedra I have been making are hollow. I thought I would experiment with putting lights inside of them. I designed a quick triangular key pattern for the latticework.
This uses a simple circuit made with a Chibitronics Circuit Sticker, a 1216 coin cell, some copper tape and, some washi tape.
Please enjoy pondering my icosa-orb.
This uses a simple circuit made with a Chibitronics Circuit Sticker, a 1216 coin cell, a reed switch and, a tiny piece of laser-cut plywood.
Process video coming soon!
