A friend of mine has a problem that the metallic connectors on the charging port gives her rashes. She is very sensitive to earrings and jewelries as well.
To allow her to wear her watch all day i created a small cap to cover the charging port. It fits very well and isn't noticeable as the edge is only 0.5 mm tall.
Fits: https://www.garmin.com/en-US/p/pn/010-12983-00#devices any device that use this charging connector and is present in the list.
Material: Medium TPU
Print settings: 0% infill, 1-2 walls.
Note: It's a small part, so make sure your flow is optimal or the piece will fit to tightly. Printer is actually Ender 3 S1 Pro but it is not selectable yet.
