Insert for SnapLock boxes to store ammunition. 

Stores 50 rounds with current settings. Parametrics can be changed to your liking or casing size. Settings I'm using for medium rifle rounds.

Parameters need to be changed on the SnapLock Storage Boxes (parametric) to allow this insert to fit. 

For instructions of how to get the values to use for the SnapLock Storage box (parametric) check the How To - Find Values pdf document. 

More pictures to come (the first one's not accurate, I used in a small box than it was meant for.) If you have comments, questions, or inquiries let me know down below or shoot me a dm.
