Locked Storage Box (Keychain)

Design of a locked box in the form of a keychain to carry a USB stick or anything. A nail or similar piece with a diameter of 2 mm and a length of 35 mm can be used for the connection of the box and lid. No other fastener is required. The inner dimensions of the box are 38x17x8 mm and the outer dimensions are 42x30x13 mm.

Since the wall thickness is low, it is a suitable choice in terms of being robust to be printed at 100% fullness. It is recommended that the cover be pressed vertically and with support so that the locking mechanism is strong.
