Variants are currently available for 3x 35mm film and 2x Fujifilm NP-W126S rechargeable batteries; I may design more for other items if requested (please provide dimensions).
Print in the most impact-resistant material you have access to (ABS preferred). Increase perimeter count until the walls are solid. The cases can be made relatively watertight (not guaranteed) by laying down a ~1mm thick bead of silicone sealant inside the groove on the bottom half and allowing it to cure before closing the case. I recommend adding a strip of 2mm thick EPDM foam tape inside the top cover to cushion the items inside. Assemble as shown in the photos.
