Prusa I3 MK2 MK3 filament holder extended guide
Description
Extended filament guide that fits on the Prusa I3 filament spool holder (http://www.thingiverse.com/thing:2565556) designed by Jasoncanning. Prevents the tight bends that sometimes causes the stiffer filaments to break when reaching the top on tall prints. Does limit positioning of the spool holder though. Modeled in FreeCAD, checked with MeshLab. Printed using Slic3r, Octoprint, and Original Prusa I3 MK2. Update: Some users had issues with the filament slipping out of the guide with larger spools. Added an additional model in which, I moved the opening to the back side of the loop to where the mount is. This allows it to flex a little and act as a hook to keep the filament in place regardless of spool size.
