Prusa Simple Angled Spool Mount v3
by QuantumConcepts, published
An updated spool mount which is long/tall enough to fit a 5lb spool from UltiMachine (and likely others). I also extended the angled support pieces to the full width of the model.
Print two, snap onto the top threaded rods of your Prusa, mount your spool on the top with a smooth (or threaded) rod.
