A filament guide to help direct the filament from an external spool to the print head without getting tangled up in anything. Designed for the Prusa i3 Mk2.
For use with separate spool holder. Works great with the TUSH spool roller found here: https://www.thingiverse.com/thing:2047554
Print upside-down with the top side on the build surface. No raft/brim or supports necessary.
Works well with the TUSH spool roller!
