Printed on a P1S - in White TPU
Default settings for Generic TPU in Bambu Studios

Printed this for the Snapmaker A350 Enclosure, it's longer than the shelf it sits on. Rather than leaving it rubbing with the metal parts, I split the bumper down the middle to "grip" the frame. The enclosure doesn't have an opening to slide the bumper in, pushed one side of the bumper in at an angle into the rail and used tweezers to push the other side in.
