Combination Lock Money Box

thingiverse

Trigubovich's original model combination lock was super cool but I wanted to turn it into kind of a fun gift box for my nephew. the face plates screw directly to the box, replacing the bottom two supports. when the lock is closed the bolt sits above the slide top lid. when the lock is closed the lid can be removed exposing a .74 dia hole 2.75 deep perfect for US sized bills. I also used Supernova's alternate knob Other tweaks I had to make to the original lock: I added a fixed peg to the two rear disks then used M3x5 screws to the backs of the disks to interact with the fixed pegs, I was having clearance issues using screws on both sides You either need M3x30 all thread or to print a lever with bars included, there is NO clearance for screw heads on the leaver. Additionally a friction fit between the 2 rear disks and the fixed rod is necessary or else the disk will spin freely, I printed my fixed rod over sized then sanded to get an appropriate fit
