Pebble Time 2 - Bumper

This bumper does not require any adhesive. It simply snaps onto the watch body and stays in place.
I'm not an engineer, so the design may not be perfect, and I can't guarantee maximum protection or durability. However, it works well for me, and I think it looks acceptable.

Printed well even on an ancient Ender 3v2 with standard 0.2mm layer height. It's likely possible to print it better by playing with the settings.
