I found the file on the bambu lab Site for modeling custom modplate or side covers. This is for the P1S, P1P, and the AMS, for all you modeling needs. 
found https://wiki.bambulab.com/en/p1/modplate-customization
[Download P1P Frame 3DM File](https://public-cdn.bambulab.com/wiki/p1p/P1Pframe.3dm)
[Download P1P Frame STP File](https://public-cdn.bambulab.com/wiki/p1p/p1pframe.stp)
I plan to use the file to make my own custom Riser for the AMS. and maybe a poop chute that can go to the right side of the machine
I used blender and freeCAD to covert the 3DM and STP File to a STL and a blend format. 

*I have not verified the scale to actual dimensions
