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

thingiverse

A super easy-to-print spool holder for the Prusa i3 Mk2/S that needs a minimal amount of filament to print and is extremely strong. The spool holder clips onto the top frame. A quick-release rod lets you swap out filament spools in no time. The 90 mm rod fits most standard-sized spools, but I've also included 60 and 150 mm versions for added flexibility. I initially tried a more complex spool holder with ball bearings, but it turned out to be a bigger headache than expected - the lack of friction ended up causing tangles that ruined one of my prints. So, I created this simpler alternative to replace it. This spool holder is designed to work seamlessly with most filament guides; I personally use this one: https://www.thingiverse.com/thing:1940114
