I designed an organizer for the included original GoPro bag (Hero 9, 10 & 11). It is the same case as the hard shell case available for purchase on the GoPro website.

The organizer is printed upright and then inserted into the bag. It fits perfectly in my bag. It has to be printed with support structures because a bevel had to be added to the bottom.

I printed it with PLA. The print bed adhesion was not a problem for me (Textured PEI Plate). However, if the pressure plate is worn or dirty, a BRIM should be set as a liability.

The following things fit in the bag:
-GoPro Hero 11
-Original battery charging station with BATTERY
-original Shorty / the handler or other handles
-2 SD cards with a clip that holds them in place
-1 space for cables, screws and angles

Cutouts have been provided for the GoPro and the charging station so that they can be easily removed.

It was also made possible to stow the GoPro with the quick change.

The 2 slots for the SD cards were also provided with a small clamping lever so that the SD cards do not fall out.
