Summary

UPDATE 2024.01.07 - Added a version with cutout for the door, so you can charge/change batteries and SD cards without taking it out of the case. Everything else is the same.

Designed this to give my GoPro as much protection as possible.
Front screen is partially protected (so you can still see status info), while rear screen is FULLY COVERED, meaning you can't use it (and won't see it unless printed from transparent material). You need to do settings from Quik or before inserting into the case.
Protects from all sides, two sides are partially open to have at least a little airflow (and of course one end has to be open to insert).

Uses stock sized mounting fingers so should be compatible with any mounting finger.

Print with flat side (where it opens, as on pic) on bed. You might try printing on its back, but it means much more support.
You might need to resize it a bit, it's designed for a tight fit, but if your printer is not accurate enough, camera might not fit or won't be stable inside.

Print from TPU, support are necessary for the lens part, others are optional depending on your machine.

Fusion360 file included, feel free to modify it for your needs.
