About this 3D model

This is a parametric OpenSCAD implementation of the Flexible Coupling created by Gyrobot (http://www.thingiverse.com/thing:38678). **UPDATES** **2012-01-24**: I made this part "Customizer compliant". **2018-01-08**: I added the possibility to choose different TOP and BOTTOM values for the shaft diameter (and related flat shaft thickness). _NOTE_: put the smaller diameter on bottom to reduce overhangs.
