Spool Holder
thingiverse
A precision-engineered spool holder that minimizes rotational friction, ensuring smooth filament feeding into the extruder with minimal effort. Optimized for 53mm Spool cores. Equipped with two high-quality 6202 bearings, expertly pressed in by hand against a solid surface for added stability. To integrate this spool holder onto an Ender 3 top bracket, simply remove the plastic tube and install a 12mm All Thread rod, measuring 110mm long. Secure it with two large washers and a nut on each side, then finish with a nyloc nut at the other end, tightened by hand to prevent slippage during printing. This ingenious design streamlines spool management, making it effortless to switch between prints with minimal hassle.
