Combination lock soft drink can cover/piggy bank

thingiverse

Assemble a soft drink can safe with an insulated cover and customizable features. Print one base, choose your desired top (standard, piggy bank, or straw hole), and attach a latch with three washers. Hang four dials in a row on the latch, each against a washer, leaving the last dial for later. Attach the assembly to the base by sliding it into the groove. Add the final dial and align it with the space evenly spaced around the safe. Slide the top ring onto the base and secure it in place. Rotate the dials to your chosen combination, then slide the latch down and tighten the lid. To lock, rotate one or more of the dials and slide the latch upwards. To unlock, align the dials, slide the latch down, and unscrew the lid. If using the straw hole top, insert the straw plug from either side to secure.
