lego bone 002

Experiment for a Customizable connector bone for LEGO Technic.
This is a 3-hole connection bone.
Why not use it for making linkages?

Updated December 2016
Added Knuckle parameter to the code. The material around the holes looked a bit thin.

It was inspired by the gorgeous parametric curved lego brick generator [thing:629875](http://www.thingiverse.com/thing:629875) by Steve Medwin.
