This part replaces the power button on a Garmin Oregon 3xx/4xx (probably also other models from the same series). Print the cover from a flexible material like TPU and the pin from a solid material like PLA or PETG.
Both parts need a bit of post-processing. The cover needs to be bend in shape before gluing it in. I used a hairdryer to give it a slight curve. The pin has to be sanded down until it sits almost flush with the case when inserted. Remove as much material and do regularly test fits until you have a good tactile feedback.

Made it a two part design to print the pin from a solid material.
