Printrbot Spool Spacer - Spool guide addon

thingiverse

This is an addon to nmackes' guide/bumper that prevents the spool from catching on the bolts: http://www.thingiverse.com/thing:636176 His design did a great job for that problem, but then I noticed the spool itself sometimes gets in the way when the arm goes way up the Z axis. I created this part as an addon that clips into the bumper from nmackes. Updated STL to fix orientation (Z and Y were swapped), I positioned the overhanging clip on the side of the fan for an easier print. WIP: I recently bought spools that are too wide (95mm) to fit properly and am working on a new model that will accommodate both the narrow and wide ones I have. Uploaded the longer one, still an alpha version as I didn't have any time to print it yet, YMMV.
