Inspired by DJI Mini 3 Pro Hollow Battery Case by gyozamonstah, but wanted something that was easier to print—and also with partitioned storage.
I've designed the inside to fit the three extra lenses/filters I carry around, plus a full set of spare propellors, incl. screwdriver. The .f3d file is included, in case you want to customize this to fit your own load-out.
I decided not to model the snap-fit release buttons, opting instead to fine-tune dimensions to achieve a snug fit, which keeps the box secure under normal circumstances (not inverted). If it's not quite a snug fit for you, I suggest adding a couple small pieces of electrical tape, for the ribs/teeth on the charging unit to grip against.
