This is a little project I have been working on. I wanted an ammo box that required no extra parts and that I could easily print in 1 sitting (Hit print and walk away). Using the below settings on my Ender 3 s1 Pro, this ammo box and lid take exactly 7 hours to print. Let me know if you have any suggestions or edits!

Detail: .2
Print Speed: 170mm
First layer Speed: 20mm
Wall/top & Bottom Speed: 50mm
Supports: No
Raft: No
Infill: 10%

I am in the works of making a 50 cal can carrying system using this base box design. Keep an eye out!
