Snap fit linkage

thingiverse

Customizable link that can snap into and around bearings. Combine them to make complex linkages like the four bar linkage shown. Use Thingiverse's customizer to change the length, or open the file in OpenSCAD (http://www.openscad.org), modify the LINK_LENGTH constant at the top of the file, render it, then export it as STL. The linkage pictured has lengths 15, 45, 45, and 60 mm. I designed it specifically for use with 608 abec bearings: https://www.google.com/search?q=608+abec+bearings
