About this 3D model

This is a mechanism to transmit rotation power between two axles that can move relative to one another but stay parallel at all times. It can take higher loads than a doublecardan joint. I need to ad a clearance parameter for the pins. The first test-print was stuck. **Generally this design needs a lot of improvement. Expect problems.** **Known issues:** ★ short pins are too stiff ★ tolerances are too thigh ★ parts are too thick it was inspired by this: http://www.thingiverse.com/thing:14060 and it is intended as a drive for my moineau pump model http://www.thingiverse.com/thing:28237 For the connector pieces the optimal length is chosen automatically.
