Robo3D Cable Holder

I based this off of the design by keraynopoylos' "Cable bundle holder for Robo3D printer" which is at http://www.thingiverse.com/thing:162100

This accomplishes the same thing. When you remove the cover from the Robo3D printer the zip tie that holds the cable bundle above the extruder is removed and thus the cable bundle is now loose and has no support.

This mounts to the size of the X carriage motor (same side as the cable bundle) and is secured using an M3 bolt, flat washer and lock nut.
