UPDATE 12 November 2023: I've received a consistent handful of messages from people who have been downloading the wrong original files so I've reuploaded the correct lid/seal files here as well.
UPDATE 13 July 2023: Added a version with an additional 0.6mm clearance on front and back for screen protectors on front/rear screens and lens. Still utilizes same lid/latch/seal files from the original model. Let me know if you have any issues with this variant and I will do my best to fix.
This is a remix of Whity's rugged box for GoPro 9/10/11 adjusted to take 2 batteries and 2 microSD cards. This is the same idea as the remix done by Joesn for the Hero 8, but my version fits the Hero 9/10/11/12 geometry.
Note: This uses the original lid and latch files from the original model. These are the 4 SD box files as the 2 SD + battery cover design is wider and will not fit. I've reuploaded these files on this page to make sure there's no ambiguity:
GoPro 11 - Rugged Box - 4 SD - Lid.stl
GoPro 11 - Rugged Box - 4 SD - Latch.stl
GoPro 11 - Rugged Box - 4 SD - Seal.stl (optional)
You will also need the M3 hardware: six M3 x 20mm bolts, and a piece of soft foam for the lid approximately 73mm x 53mm x 8mm

Redesigned to fit multiple batteries and fewer SD cards
