Thread spool holder

I took the original design and shrunk it down in Slic3r.
75% and printed 7sets at a time. = 5h:25m
50% and printed 15sets at once = 4h:43m

The Closet in my lab has unfinished walls so the space between studs is the perfect place to mount things without sacrificing space.

I super glued the units to the drywall. i didn't want screws sticking out of the face side of the drywall.
