Filament Tube Guide for Prusa I3 MK2

thingiverse

This is a 6mm OD Teflon filament tubing guide designed to minimize exposure of 1.75mm filament to tropical high humidity. A standard four-cable tie system holds the tubing firmly in place within the guide, which easily clips onto the Prusa i3 MK2 extruder. The opposite end of the tube is directly connected to a dry cabinet for optimal storage. To load filament into the printer, first slide off this guide, then feed the filament through the tube. Load the filament normally as you would with any other printer. Finally, simply slide the guide back on. Note: For best results, use only Teflon tubing with this assembly. Normal tubing may cause feeding issues due to excessive friction.
