Prusa i3 filament reel roller, bracket and guide

thingiverse

My Prusa i3 features two metal filament mount arms on top and the rod for the filament just slots into two grooves, which would fall out if I get the balance wrong with just one reel at one end. I created this set of parts to fix this issue. Firstly, the long brackets fit over the top of the arms and have holes for two lengths of 5mm piano wire. The higher has the end rollers attached while the lower piano wire has the filament guide, two washers, and the roller, made in two parts for ease of printing. Bearings are 5mm ID, 10mm OD, and 4mm thick. This is all original work, not based on anything else out there.
