My concept for a quick-change adapter for easily attaching/detaching the AMS feeder from a Bambu Lab P1P. (It also works great on the X1C!) This lets you easily detach the AMS to manually feed filament from an external spool. #ThangsBambuContest

My design skills are amateur at best, so there's definitely room for improvement here and I encourage anyone to evolve this concept. Please see the Areas for Improvement section below.

Bill of Materials:

1. PC4-M10 Pneumatic Fittings - Amazon Affiliate Link
2. 10x4mm Disc Magnets with 4mm Hole - Amazon Affiliate Link
3. 6x3mm Round Magnets - Amazon Affiliate Link
4. PTFE Tube - Bambu Lab Store

Printing Instructions:

• I really like eSUN PLA-ST filament for projects like this because it seems to be a little more pliable and less prone to cracking.
• Print using 100% rectilinear infill with 0.16mm layer height.
• Print the objects using the orientation defined in the STL file. You will have to add supports below the base for the device-side coupler. Painting them on this area with Bambu Studio works best.

Assembly Instructions:

• The magnets should easily friction-fit into the holes, but feel free to add a drop of superglue if necessary.
• Stack two disc magnets for each of the couplers.
• If using the countersunk magnets, the concave side should be on the device coupler and the PTFE tube should be flush. The flat side should be on the AMS side and the PTFE tube should protrude a bit so it aligns with the tube in the other coupler.
• There are no threads for the pneumatic fittings because that is definitely outside of my Tinkercad skill level. This is definitely something that can be improved. However, I mounted the couplers in a bench vice and carefully tapped the pneumatic fittings in by applying pressure while turning with a box wrench. (This is why I recommend PLA-ST or another "tough" filament.)
• Although this kind of defeats the purpose, I have included a design for a "brace" which clips onto the pneumatic fittings. This just gives extra security in case the filament retraction overpowers the magnets.
• A picture is worth 1,000 words so take a look at those for more clarity.

Areas for Improvement:

1. Threads for the pneumatic fittings would be nice.
2. I'm not thrilled with the hole magnets. I would prefer they were not countersunk for increased magnetic strength, but these were the best I could source on Amazon. If the magnets were stronger, the brace wouldn't be necessary.

Attribution: The coupler design is my own original, however the clip & brace are based on the design by G4ZO on Thingiverse. Thanks dude!
