OpenSCAD U-Joint Library

This is a simple U-Joint library for OpenScad.

Usage is pretty simple, specify the diameter and you'll get a ujoint.

*//create a ujoint with a radius of 20mm*
*ujoint(R=20);*

Printed at 20mm/w a .35mm nozzle it seems to work pretty darn well. You should be able to simply print this part, and remove the support material and it will work. I printed the support material every 2mm

I've tested this with radius of 15mm-40mm and it seems to work pretty well.
