Parametric Shaft Coupler

I remixed my Parametric Rigid coupler from http://www.thingiverse.com/thing:964671 to create this. It is essentially the same as that, but I took out a couple of variables that were specific to its use.

There are probably a few other couplers out there, but having it parametric makes it very easy to make just the right coupler you need.

I used 2 - M3x14mm bolts & locknuts for the 5mm to 5mm that is shown printed in Yellow PETG.
