These are corners caps I made for the holes in each corner of my Da Vinci 2.0 Duo printer. I made them fit with no gap next to the wall. I made four different sets of caps to suite different tastes: I also improved upon my previous design a bit by rounding the edges of the plastic that snaps into the hole to make it easier to insert. Just print and enjoy :) Update Also check out the side covers I made that complement these corner caps: http://www.thingiverse.com/thing:721623
