Tray-hung spool holder

Filament spool holder designed to slide into a whiteboard tray aluminium extrusion already attached to the wall.

Note that the model is not super stiff, and a threaded rod with a spool will slide in one direction until it falls down — as such you should use self-locking nuts on the spool rod. (Or you could stiffen it up by printing thicker parallel parts, and a stiffer support bar.)
