PRUSA upgraded filament holder
cults3d
This is my take on an upgraded filament holder for the Prusa printers. It uses 4 roller bearings for smooth operation. The geometry of the rollers prevents the spool from ever falling of the stand. At the same time it is very easy to perform filament changes, as the spool is not constrained on either side. The whole construction just sits on top of the Prusa frame. NECESSARY COMPONENTS: 4xRollerBearing (15mm outer diameter, 6 mm inner diameter, 5mm thickness) 2xM3 Nut 2xM3 Screw (at least 16 mm lenght)
