About this 3D model
Customized version of http://www.thingiverse.com/thing:53451 Created with Customizer! http://www.thingiverse.com/apps/customizer/run?thing_id=53451 This is my second attempt at modifying the original bearing. I am happy to report that on a RepRap Mendel this printed and functioned exactly as expected. The changes from my other bearing were decreasing the tolerance form 0.5 to 0.3, using a smaller angle, and increasing the amount of twist in the hearing bone.
