Hi! This is my first CAD model ever. It took some math work to figure out rotation axes, angles and such, but i think it turned out fine and it was worth it.

It's trickier to assemble than it looks!! You have to figure out not only where to put each color, but also the angle.

If you get right the insertion angle the pieces should come in with relative ease. Same thing goes for the disassembly. I may prepare a looser fit version anyway.

Once assembled you get to admire this math sculpture for as long as you want ;-). Or you can put it apart again and repeat.

In the files you will find two versions:

• Version 2: This is the interesting version and the one that's actually a puzzle. Prints fairly well without any supports.
• Version 1: My first tentative approach at modelling it. It comprises a polyhedral core to which the “spikes” attach (glueing required, sorry). No supports needed for the pieces, but for the core I had to resort to a raft and supports.

For both versions I included the source code in OpenSCAD format, so you can adjust the size and clearances if needed or play with it as you like.

PS: I'll try to get better photos, sorry.
