G2S Universal Effector M3

By request, these are versions of my [Universal Effector](http://www.thingiverse.com/thing:1356159) modified for M3 rod hardware instead of the G2S stock 6mm mounts. I have included both the standard size and the enlarged version.

UPDATE: Added similarly modified version of my [3-Bearing Carriage](http://www.thingiverse.com/thing:1620524) to complete the set.
