About this 3D model

*Update Jan 9, 2015 New filament guide works at faster speeds (tested at 30mm/s) and seems to work alright. I would still recommend 20mm/s, at hotter temperatures than they recommend. Place filament guide as pictured above, so it is touching (or almost touching) the G2 pulley. ---------------------------------------------------------------------------------------- First attempt at making Printrbot filament guide for Ninjaflex. Prevents filament from tangling up.... Tolerances need to be smaller. Still requires very slow print speeds... like 10mm/s speeds for everything... at least that's what I've successfully printed at with it so far. 20mm/s seems too fast. Print temp 240.
