Better Ammo Boxes

I was unsatisfied with the existing options for ammo boxes, so I made these.  In my opinion, most designs are inefficient, requiring more material and time then is strictly necessary.  These, I feel, do better.  I have maximized strength while minimizing print time and material usage.

Comparing the 9mm box to some other popular 50round 9mm boxes, sliced with identical settings:

My Better Box - 60g filament, 1.75hrs

“9mm Ammo Box” - 77g filament, 3hrs

Slim Ammo Box v2.0 - 78g filament, 3.75hrs

Rugged 9mm Ammo Box - 90g filament, 3.5hrs

Print parts as provided.  No supports needed.  Arachne slicing algorithm recommended.  ABS/ASA or PETG is recommended.
