Nema 17 'captive washers' spacer
Published on December 12, 2012
A very simple Nema 17 motor spacer for 3-hole mounts. I needed to space my motor away from my Kuehling extruder (http://www.thingiverse.com/thing:18379) because I used a very thin washer between the large gear and the bearing. I also needed to space my X motor away from my X-end (http://www.thingiverse.com/thing:16291) a bit to get my pulley to fit where I wanted it. In both cases I just stacked washers but these were a huge pain to reinstall vertically with the machine assembled (which I had to do a bunch of times to get everything 'just right'), so I made this. The thickness of the spacer is a parameter in the scad file. It's the first useful thing I ever drew in OpenSCAD and the second useful thing my printer ever printed.
Set thickness, slice and print. The two I made fit correctly.
