Reverse Bowden End Cap

thingiverse

I have a Prusa Mk3 printer and created this amazing reverse bowden setup where the end point mounts to the upper right of the frame. I used old M10 tube fittings, but they only kept the PTFE tubing from pulling back out. So when I removed the filament, the tube would come through with it and I'd have to adjust it all again. I quickly designed a simple end cap piece that screws in from underneath, giving me an end point for the tube and a nice little hole to put the filament when feeding it in. I've included the scad file so you can tweak it to your liking - note that it uses the nuts and bolts library here: https://www.thingiverse.com/thing:965737 to do all the real work.
