Bangle Bearing

pinshape

I always have a copy of Emmett's brilliant Gear Bearing out on the coffee table, and it's become an instant conversation starter and introduction to 3D printing. Recently, someone I showed it to had a bold idea - they thought it would make an interesting bangle. While its fashion potential is debatable, I saw it as an exciting challenge for my printer. I'd already taken inspiration from Sal's design of gear bearings with large circular holes instead of small hexagonal ones (http://www.thingiverse.com/make:26306). So, I decided to push the limits even further. I've uploaded the modified .scad file, which keeps the design fully parametric, and also included a copy of the STL file that's been optimized for my printer's tolerances. Check out this video of the bangle in action as it works seamlessly as a gear bearing (although it might not be winning any fashion awards!) http://www.youtube.com/watch?v=Qt39vLo5l90
