Watertight Modular Flatpack Storage

A step up from my previous design, the Watertight Battery Flatpack, this is a slightly thicker version with modular inserts and a grid in the bottom to keep them from moving around. Measuring internally at 3.25" wide x 4.6" long, the case is for storage of small items while separating them internally.  Perfect for medical (as pictured), or fire starting materials, cooking supplies, what have you.  If you're out on a multi-day hike and need something that can handle rain, but not just be one container with everything rattling around, this is the solution.

No hardware needed, no supports needed.  No AMS required unless you're utilizing the name tag, and even that could likely be done with a manual filament change.  I recommend printing in PETG if it's going to be exposed to summer heat, but otherwise, your choice of filament is fine.  Print with 4 walls, 15% infill.  Delete the inserts you don't want and duplicate the ones you do.  The tray is 2 slots wide by four slots long, so two of the 4x4 trays would work, or 8 of the 1x1 for example.  Mix and design as needed for your purposes.

Comments, critiques, requests welcome.  Enjoy!
