Ok here is new newest and most recently updated BambuLabs AMS PTFE adapter v2
It's highly recommended to use 3-4" of extra PTFE tubing to reduce filament rolls from jumping inside the AMS when they get lower in material
---------
In progress: (currently in design and testing phase)
- PN4-M10 fitting - completed
- PN4-M6 fitting - completed
- Universal fitting - completed
- TPU - in progress
- Modified M6 and M10 for better AMS clearances - in progress
M10 and M6 versions are an extremely tight fit to the AMS lid
Print settings:
Materials PLA and PETG
- Supports: None
- Walls 3
- Top/Bottom layers: 4+
- Layer height: 0.1mm (highly recommended for overhangs)
- Infill: not required
- Brim: that's up to you
Materials TPU : Use the TPU model
- Requires TPU calibration for cleaner overhangs (settings may VARY)
- Supports: None
- Walls 3
- Top/Bottom layers: 4+
- Layer height: 0.1mm (highly recommended for overhangs)
- Infill: not required
- Brim: that's up to you
- Fitting clip is included in the file (you'll have to push the fitting through the top)
Materials ABS (currently testing)
- Supports: None
- Walls 3
- Top/Bottom layers: 4+
- Layer height: 0.1mm (highly recommended for overhangs)
- Infill: not required
- Brim: that's up to you
- Scale X/Y @99%
Small tab to the bed is all that's required
File naming:
BL - BambuLabs
PN - ## - Pneumatic Fitting / ## is OD size (ie PN-04 is 4mm OD)
M# - thread sizing ie M6/M10/etc.
PTFE - Type of tuning to be used
EXAMPLE: v2.#.# - PN-04-M6-PTFE
- v2.(variant).(variant version) - Pneumatic fitting - 4mm OD - 6mm thread - PTFE tubing
Materials required:
- PLA, PETG, or ABS
- PTFE 4mm OD (longer lengths off the adapters have been shown to work better with smaller reels and ones that are less than 75% full with less overall drag angles and snagging on edges of PTFE tubing)
- PT4-M6 or M10 based on versions below
or
- AMS feeder replacement part per feeder (we want the bottom pneumatic fitting and the screw)
or
- Universal: 4mm OD hole for short PTFE tube or for abrasion resistant material

Assembly:
- Install the adapter onto you 1st stage butter (it will be tight and you'll likely hear x2 small pops to seat it properly
- place the collar around the pneumatic fitting and gently slide it into the back hole and press the fitting into the hole
- place screw into hole and use an allen key to secure it
- slide in PFTE tube until it is all the way in (its highly recommended to use 3-4" of extra PTFE tubing to reduce filament rolls from jumping inside the AMS when they get lower in material)
- Start printing and enjoy!
