Ian's updated reel roller
thingiverse
To enhance Airtripper's superb Reel Roller (http://www.thingiverse.com/thing:21435), I made some adjustments by counterboring screw heads and adding nut pockets for a smoother appearance and compatibility with M3x25mm screws. Previously, I only had 40mm screws, which looked comical due to their excessive length. For this project, you need to print four left and right parts. As for the components, gather eight 608 ZZ [8 x 22 x 7] Roller Skate Ball Bearings, eight M3 x 25mm Hex Head Screws, and eight M3 Nuts. This spool holder is perfect for Prusa Air; I installed it sideways above the filament guide slot in the top plate, slightly offset to the right to allow room for extruder wiring movement.
