Zim Filament Winder Sprockets

thingiverse

A breakthrough emerges for easily refilling Zim filament spools. By simply popping open the casing, access is gained to the internal filament spool. Tactile engagement with the spool's sides enables the top to be swiftly detached. These ingenious sprockets can now be effortlessly attached to either side, allowing for secure connection via a hex shaft to a drill, while the other sprocket remains graspable in one hand. Simply insert the new filament into the convenient hole at the base of the spool and rewind it seamlessly back onto itself. To ensure the process runs smoothly, verify that the small black O-ring is not lost in its intended groove at the neck of the cartridge.
