MTM Organizer Trays
thingiverse
Organizer trays for the 50-cal size MTM storage boxes. These rest on the upper ledge of the box bottom while still allowing the lid to latch and seal. They're named for their nominal inside length but the numbers aren't gospel. The 150 size is the one in the photos. *EDIT* There WOULD be photos if Thingiverse allowed bigger than 500kb for .jpg's. The 200 size is about the biggest one can print on an Ender 3 or similar. You can fit a 150 and two 65's, or a 200 and one 75 in one box. They're currently about an inch deep. I'll probably add deeper trays later.
