About this 3D model

I bought a couple geared steppers from Trinity Labs which ended up being the shorter shafts. Like a normal hacker I took a design I liked and worked it into fitting what I have on hand. Sketchup did a surprising job with this :P V1 has the same exact holes as the original Tinkey Struder just with a wider back to line up the shaft a bit better. (I hope, currently testing) V2 has a longer base to fit mounts for greg extruders. I really needed the V2 only but figured I'd release them both.
