V-Slot Snap Cover

This cover is designed to snap firmly over the v-slots of aluminum extrusions. (2020, 2040, etc) This can be done for either aesthetic reasons, or to conceal wiring ran through the slots. Because of the small details of this design, I recommend printing in .1mm detail. These parts have a nice, firm fit. They should snap right in with a firm push.

While not a direct remix (I designed these from scratch), after a failed previous design (one which had to slide in from the end), I did draw inspiration from this thing: http://www.thingiverse.com/thing:944921 (I had difficulty getting this one to stay in place, and it kept popping out.)

Add new file, "Strain Relief - New". This is a new part I'm using at the top of the 2040. This new part has a place to tie the wires to for strain relieve, as well, as accomodating my printer's spool holder and a mount point for a LCD case I've desinged: https://www.thingiverse.com/thing:2067529
