We noticed an issue with the battery doors on our Blackmagic Design Pocket Cinema Camera 4Ks. After opening/closing a few times, the doors start to randomly flop open on their own. After some testing we decided this was due to the weak part used to latch the door closed; fortunately, it was plastic, so we just made our own :3
This beefed up version is more reliable, so we'd recommend swapping yours out too. There are just two small screws covering the mechanism inside the battery door, and nothing tricky about making the swap. Cheers!
Print as oriented, with supports. We use Colorfabb XT but your favorite PET filament should be fine.
