Bambu AMS Feeder PTFE Adapter v2.0

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 pess 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!

Notes:

• this is a free to use model and you assume all risk and responsibly of installing the adapters into your units.
• This is designed yo help limit the risk of excessive wear and tear on the 1st buffers and isn't a permanent solution to the issue that it prevents.
• This isn't a BambuLabs sponsored product and is designed solely to help the community and to use at their own risk
• Not every material will work and its best to test your machine tolerance and fit as needed (this model has a 0.125mm tolerance and is considerably tight in all fit tests)
• Please like and share with your friends

Now get back to printing and have a great Day!

Revisions:

Jan 10:

• Changed the original design to make it more durable and updated the locking clip for easier installation and strength for the screw
• Renamed the files and will have a consistent file system as new parts and adaptations are designed, tested and released

Jan 15:

• Tilted PT-04-M6-PTFE and M10 - 10 degrees into the AMS and it now clears the lid and closes without issue. (flat piece of edge needs to be facing the front)
