Tevo Black Widow - Top Mount Spool Holder

A spool holder for the top of your Tevo Black Widow 3D printer. Print two copies of the STL, and use a piece of pipe between them. These may fit snug enough to not need it, but for safety you will probably want to use a bolt and t-nut to secure them to the frame so they don't wiggle around and drop a spool of filament on your print bed.
