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:
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:
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.
