Spool holder with detachable rod - for Prusa i3 Mk2/S

myminifactory

The Prusa i3 Mk2/S gets a straightforward spool holder that's effortless to print. Minimal filament is needed, and the result is incredibly sturdy. This spool holder attaches directly to the frame's top surface. The rod comes off easily, allowing for quick and trouble-free filament spool changes. I've included three different rod lengths: 90 mm, which should fit most standard spools, plus 60 and 150 mm versions for added flexibility. Initially, I opted for a more intricate spool holder featuring ball bearings to minimize friction. However, it soon became apparent that the lack of resistance actually led to tangles that ruined my prints. This prompted me to design this simpler alternative.
