D20

This is a sideproject i made for my girlfriend. The original (unfinished) project is an icosahedron lamp, similar to nanoleaf but in a polygon shape. This will be posted on my profile when its done. She asked me to turn my prototype into a D20, so i did!

The model is easy to print and easy to assemble.

To make an Icosahedron you need to print:

• 30 studs 
• 12 hubs
• 20 pads/tiles

This sounds a lot, but can be printed in just a few hours.

Assembly instructions:

1. Print 3 studs and 3 hubs first! This can be done in either 0.15 or 0.2mm layer height. Assemble them into a triangle. The studs should slide smooth into the hubs and should not require any glue to stay together. If the fit is too tight or too loose, try to adjust your outer wall inset.
2. When the structure holds together, but can be taken apart easily, print the remaining studs and hubs.
3. assemble them into an icosahedron skeleton, this part should be easy but watch out to not put too much force on the studs! the long lever can create a moment that breaks the hub.
4. the tiles could be printed in 1 color and get a paintjob in post proces, or can be printed with a filament swap. The filament swap should happen at a height of 0.8mm or higher. (on a 0.2mm layer height this is the 5th layer).
5. Assemble the tiles by pushing each corner into the slot on the hub. You can slide the studs a little bit out of the hub to create a little space for the tile to slide into each corner. The tile should be able to flex a little bit so you dont have to fully disassemble the icosahedron.
6. try to follow the D20 layout during the assembly for an accurate representation.

To give it a magical twist, i used the eastern arabic numerals.
