Working Combination Lock

I made this for a Uni project earlier in the year so I thought I'd add it up here.

It's an actual working combination lock!

I have included 4 different numbers so you can choose your own order of numbers and combination.

All it needs is 2 screws to assemble it together.

You can use an optional spring to make it spring open also.

I printed my model with PLA at .15 resolution with 35% infill.

I used supports where the overhang is on Side 1 and Side 2
