300AAC Ammo Box (stackable)

UPDATE 3/18/24: I have split this into two models, the box and the lid. I have also made it taller to better accommodate different types of ammo. These I've uploaded as STL files. The STP is the original design.

Thank you everyone for your feedback.


This is a simple ammo box I designed for 300 Blackout. It's the same design as 223/5.56mm I just changed the embossing.

I used normal supports for the lip over hang and the base lip. I tried organic but the proved difficult to remove and left the lip sort of chewed up.

I didn't really need these. I bought ammo in bulk and wanted something more than just loose rounds in a cardboard box. Also I am learning Fusion360 and this was a fairly simple project to learn on.

Is this the best ammo box out there? Probably not. Is it the best it could be? Also probably not. Am I happy with the way it turned out? Absolutely.
