I noticed when printing objects in the rear-right of the bed of my Bambu P1S, the cable chain would periodically smack into the metal frame and make it sound as if something was not right. While I don't think it was damaging anything, I decided to make a TPU bumper to absorb the blow and prevent the noise.

I added two insets for 20mm x 2mm magnets since I had those on hand, but the model is a nice snug fit into the frame, so the magnets are definitely optional. If you do use the magnets, they'll need a little glue to hold them in place.
