Platonic solids w/ lasercut faces

This started because I wanted to make my own copy of Buckminster Fuller’s  Dymaxion Map. Lasercutting mitre joints & gluing them leads to big seam lines on the map, as well as being hard to hold while gluing. Instead, I decided to make a row of holes and try sewing the faces together:

If you look closely, you can see the exact limit of my patience. 

But the stitching was a bit time consuming, as well as being difficult to retighten.

Instead, I had the idea of using 3D printed vertices, and screwing lasercut tiles into them:

With a bit of playing around with angles, and parametric design, I made the whole set:

Clockwise from top left: Icosahedron, Dodecahedron, Cube, Tetrahedron, Octahedron. 

I’m pretty happy with the construction method. Sure, it’s not exactly light on screws, but I rather like the aesthetic, and it’s extremely strong. I can stand on the icosahedron and it takes my weight with no problems.

Also, the nice thing about this approach is that to make a larger object, all you need to do is recut the wooden parts, and the 3D printed vertices can stay the same.
