Print in Place Expanding Circular Linkage
thingiverse
Expanding circular linkage, that can be 3D printed in place as an assembly without any supports. It's similar to a Hoberman sphere, but in two dimensions. There are other expanding circular linkages out there with better capabilities, but this model is designed to showcase the "print in place without supports" concept. The links are engineered to rotate freely, yet remain securely intact. This design fits snugly inside a 140mm x 140mm test bed. A demo video is available on YouTube! https://m.youtube.com/watch?v=gLEJO7mUbT8
