Print Profile(4)
Bill of Materials
Description
Holder for the new 4-in-1 PTFE Adapter II mounted on the back
The new 4-in-1 PTFE Adapter II ships with the Bambu Lab H2C
The adapter is also available via the Bambu online shop
The design of the adapter has changed and it now also offers replaceable filament cleaning pads
The cleaning pads can be changed without removing the adapter from the holder
I tested the new adapter on my H2D and H2S it is also compatible with both printers
Bambu Lab offers it as a spare part suitable for the H2C
The new version of my holder for the previous PTFE adapter has now been adapted accordingly
The new adapter can simply be clipped in and thus secured
Screws are only needed to fasten the holder to the back wall of the printer
For this, please use two ISO 4762 M3x12mm cylinder head screws
2-fold version for the H2C & H2D as well as 1-fold version for the H2S
Printed from PETG with 3 walls and 15% Gyroid infill
Update 22.12.2025:
Newly added, versions with receptacles for the original Bambu Lab PTFE coupler
Update 19.01.2026:
Revised reinforced versions v2
The geometry has been revised and reinforced, making it more stable overall
Please ensure that the hoses are laid correctly so that no excessively tight bending radii etc occur
Otherwise there may be problems with the filament feeding
The two hoses from the PTFE adapter to the filament buffer should be chosen to be approximately 500mm long
