AMS Lite Feeder Guard and PTFE Connector

v2.1 now available!

v1 could prevent the feeder from properly engaging if installed wrong (did this myself on 1 of 4), so I've replaced the profile.

v2 resolved the above issue in my testing. This release also includes both PLA and PETG options, I prefer the PETG.

v2.1 improved how the PTFE seats itself. It will now seat directly against the feeder instead of in the adapter. I am still running test prints to ensure this is the better option.

I wanted to run PTFE all the way from inside the Sunlu S4 to the AMS Lite.

I went through a few iterations of these, but these were the first that worked well enough that I wanted to post for others to use and get some feedback.

The feeder button needs to be partially depressed to expose the entire rim for both ends to snap on. It is a snug fit and needs a little force to clip on. Much nicer install experience with PETG.

I do not recommend attempting to speed this up with higher layer heights or the tabs and threads may fail, but of course feel free to experiment.

These accept PC4‑M10 pneumatic push fittings with an M10/6mm thread. I can make variants by request.

I have another version without the push fittings, but I wasn't confident in the connection. For how easy these are to come by, I decided this was the better solution.
