This is remix of :
Bambu P1P 10x11 Drag Chain Frame Adapter - Untested by ktothestank | Download free STL model | Printables.com
The original by : ktothestank (Thanks for your work)
I increased the cutout for the drag chain so it actually fits a 10x11 (inner dimension) chain e.g. the following:
I also added some small cutouts at the bottom so you do not have to touch any “likely” important holding screws for the left back motor.
Please make sure to remove the original Bambu Lab PFTE tube holder in the back before mounting this piece as its screw blocks the insertion of the module.
