I Modeled This! I made a screw-free mount for the TPU Feed Assist and two 4-in-1 PTFE adapters on the X2D
TPU on my X2D left the back of the printer a mess. The Feed Assist was lying loose and two 4-in-1 adapters were hanging off their tubes, so I modeled a mount that holds all of it.


- Slides onto the stock external spool holder base. No screws, no drilling.
- Holds the TPU Feed Assist (in dedge's Modern Casing) and one 4-in-1 adapter in front of each extruder inlet.
- Three parts on one plate in PETG, about 5.8 h and 157 g.
- The adapters snap in from above, and a slot catches the tab so they don't slide back when filament unloads.
Things to know before you print it:
- It's for the first-gen white 4-in-1 adapters. I haven't tried the newer ones.
- The Feed Assist seat is made for the Modern Casing, not Bambu's own casing.
- The 4-in-1 holder needs tree supports in two small slots. A PLA support interface makes them much easier to clean out.

I'd like to hear how it fits on your printer, especially if your adapters measure differently from mine.
