This is an approximate remix of Family Joules's "Apache 3800 37mm Storage grid"
This is for an Apache 4800, and can hold up to 70 37mm cartridges that are just shy of 5 inches oal (4.921in or 125mm) 5 inch will stand a little proud by a couple mm, but should still be positively retained.
All parts are printable on an x1c size print bed.
uses M5 hardware, I recommend countersink but YMMV
This is a DIY project, set it up how you want to, use epoxy or what ever else you feel is needed.
