Adding a little stand and lighting the first pixels.
I wanted to lift the icosahedron a little bit up so I made a little stand for it. To keep the triangle theme, I made an octahedron. This gave me 6 more triangles to put an led in, which will bring the total lights to 25.
Here’s a dxf file with the cutout for one module. It’s different than for the icosahedron since the internal angles are different (duh).
