If you install a cable chain assembly to P1P, you will notice a new bump now appears on the inside wall of the P1P unit (picture #1).

If you try to use the regular AMS holder provided by Bambu, you will notice it cannot sit in place, as the new bump prevents it (picture #2).

Therefore I designed a new version of the left AMS holder, with a hole in the middle, to be able to sit properly after cable chain assembly has been installed (picture #3).

The part from the right side, remains the same (picture #4).

Technical info:

• This is also backwards compatible, so it will work even if you don't have a cable chain assembly.
• I recommend printing with 100% infill, in order to increase toughness, and also weight (so it's more stable and less likely to fall accidentally).
