Micro M3D External Filament Guide

M3D filament guide feeds the filament off of large and small external filament rolls while providing a counter bore suitable for 5mm OD PTFE tubing to go between this guide and the print head.

It is a snap fit over the plastic body of the printer.

I've included Solidworks (2015), Parasolid and STL file formats here

UPDATES
(12/2/2015): updated files to REVf which is easier to get on and off of the printer
