About this 3D model

Improves the Original Prusa MMU2S Spool Holder leading to smoother loading and unloading. Reduce unwanted friction! Can be used with or without buffer. (Or run it without MMU and implement a filament guide) Works great with 1kg spools. Works with 250g spools too..just make sure it is orientated properly in order to prevent the spool from tipping over. Plastic on plastic contact decreasing Dynamic Friction compared to plastic on metal contact Install is simple. Remove endstop and bearing. Slide both ends onto metal rod Reinstall bearing and endstop
