3030 Bowden Coupler

3030 Bowden tube couple for M6 or M10 threaded quick connects.  

Designed for the same offset spacing as the BTT Filament sensor w/ bracket.  I used this to replace the filament sensor, as I was constantly getting filament stuck unloading or loading.  

Pass-through fittings should be used so that the ends of the PTFE tube meet in the middle of the mount.  Chamfer in the ID to make a smooth internal transition.  

Print 4 walls in PETG, ABS or ASA.  There is a thin single layer over the hole on the bottom surface to eliminate the need for supports.  That can be broken out with a sharp tool.
