This project was created for the MTU MSE4777 course as my Big Money Project, aiming to provide a low cost solution to a high cost product.
This ammo container holds 100 9mm rounds and locks at one end. The tray and outer case are modular and can be scaled up or down by changing the length, width and height. The insert can also be scaled but the holes will dissappear as the insert gets smaller. This device is intended to replace a more expensive locking ammo case along with the easier usability due to the sliding tray, allowing the user to pull out the tray a certain amount and flip to recieve a small amount of bullets.
How to assemble:
Place insert into tray and make sure that the insert rests on the elevated sides of the shorter ends. Load rounds into the 100 holes of the insert and the tray will support them. Load the tray into the outer slide and secure the lock through the holes on the outside of the tray and outer slide.
Outer Slide = 11 Hours 48 Mins (0.20 mm layer height, 122.18 g with support)
Tray = 5 Hours 53 Mins (0.20 mm layer height, 75.95 g with support)
Insert = 2 Hours 7 Mins (0.20 mm layer height, 15.86 g)
Total print time = 19 Hours 48 Mins (214 g with support)
3D printer filament (PLA) = 214 g @ $20.00/1000 g $4.28
Masterlock = $3.17
Total = $7.45
Commercial equivalent = $13.15 (box plus lock)
Cost savings = $5.70 (43%)
