PTFE M10 Wall Mount

thingiverse

I install my spools on the wall and require a method to also mount the end of my PTFE tubes. Since the direction that the PTFE should draw from the spool changes based on how full the spool is, I need something that adjusts pitch as required. This prints easily and then attaches securely. The angle of the holder's opening locks in the pivoting M10 coupler for regular use (and gravity) but is also easy to remove by rotating the coupler to a more extreme angle. This allows me to feed a new filament spool in easily, or simply detach the spool from the wall while it is still threaded. I'm using this pack of 10 PTFE M10 couplers from Amazon (US). My personal application is to complement the use of the must-have Prusa MMU2 PTFE Holder M10 Passthrough Adapter mod for the Prusa Multi-Material Upgrade (MMU). The above Amazon link provides 10 couplers, but the above-linked mod only requires 5. This will use one of the left-overs, or all 5 remaining if doing 5 filament feed tubes. Note that the thread I am using in this print is metric 10mm diameter and 1.0mm thread pitch (ISO Metric designation M10x1) and while the M10 couplers from the above Amazon link fit nicely, there is reason to believe that the actual couplers are using some non-metric thread pitch instead. Regardless, I can report that the couplers fit very firmly in this print. Update: The coupler now prevents the PTFE tubing from "moving" up when pulled.
