6.5mm Grendel 20 Round Ammo Box

thingiverse

Remix of Vilcoyote77 7.62x39 50rds box, but it has been heavily modified. https://www.thingiverse.com/thing:4104794 Unfortunately this will likely cost you more in material that it would be to buy an MTM cartridge box, but there aren't any MTM boxes that fit 6.5 Grendel well. 7.62x39mm is the same in case diameter and case length, but Grendel is often loaded longer. Posting as work in progress, as I always have to file/sand the parts to fit. In CAD, there is enough clearance that the lid should fit, but the printed lids always fit tight. Designed to use as little material as possible, but it will take a long time to print still, so I wanted to make it sturdy enough that it won't break, requiring a reprint. I made it large enough so that you should be able load long enough for the bullet to touch the lands, and still have the ammo fit in the box. SAAMI spec or factory ammo will fit with a good amount of room to spare. You could also cut some foam to put in the lid to keep the ammo from rattling. Fired (or prepped/primed) shell casings will sit lower than live rounds, but internal supports will hold the case at the taper, so you will still be able to grab the rim to pull them out. Fusion 360 CAD file is a mess, but it's there if you want to try modding. I will post the 50 round box after I confirm the modifications on the latest version.
