Hanging filament spool holder

A simple spool holder designed to be mounted on an overhanging beam, and facing out, for an enclosure made with a perimeter of beams. Fits a standard 2x2 (1.5"x1.5" actual) piece of lumber with 4 #6 countersunk wood screws. Uses a short length of standard 4mm OD PTFE (a little less than 12") to guide the filament from the spool to an appropriate exit direction and hold it when not in use, and there are holes in the model for unreeling on either side. The holder is configured for spool loading
