Filament Guide for Mendel90 - fits on a 3mm sheet

thingiverse

I modified my filament holder so it wouldn't get tangled up by the upper right Z axis. I built an OpenSCAD thing that clips onto my Mendel90 and keeps the filament in line. It'll likely work on any 3mm plate, but if you need a different size for a 5mm acrylic sheet, adjusting it should be straightforward. This thing was done in a rush: no fancy optimizations or rounded edges here. Just simple cubes and cylinders. Two plates go on either side, one ring keeps the filament on track, and a crossbeam in the middle provides stability. You'll need to print four parts and assemble them, possibly securing it all with some hot glue.
