Airsoft Ammo Can/Box

I designed this model on TinkerCad and it has not been test printed. I would love some feedback letting me know how it works, and if it needs tweaks. Assembling the model takes under 5 minutes.

1. Line up the upper lid with the lower box
2. Slide in the thin cylinder in through the holes of the upper and lower
3. Apply glue to the outer pieces of the hinge if the cylinder hinge piece wiggles and slides out
4. Load up your bbs of choice
5. Screw on the 2 pieces into the holes at the front of the box with the square piece on the bottom and the circle piece on top.
6. Enjoy

Happy printing!!
