I adapted a good design of the AMS holder (e.g. to a wall or a cabinet) https://www.printables.com/pl/model/438001-wall-mounts-for-bambu-lab-ams to the latest type of AMS, which has wide spacing between reinforcements.
The author remixed this model.
Bambulab produced several versions of their AMS (for P1p/P1s/X1/X1c) - at least I know 3, differing in the base of the housing - different indentations (vertical reinforcements)
Oldest V1 have spacing:
31.5mm - 2mm - 45mm - 2mm - 47.3mm
next V2 (popular):
39mm - 2mm - 42mm - 2mm - 42mm
newest V3 (shipped in end of 2023y)
66mm - 2mm - 82mm
This is mount made for V3
