3D model description

It's a box with a lock. It has 10 bolts with 5 numbers. So there are 5¹⁰ = 9,765,625 possible combinations.
The numbers on the bolts range from 0 to 4 and you select the number by moving the bolts on the sides of the box. The box will only open if the correct number combination is selected. Once your box is open, you can disassemble it and change the combination of numbers required to open it.

I made a mark on one side of the box (the triangles) this way you can better note the combination of the box.

The volumen of the box is about 30*48*62. But you can probably size the box up.

I made a vidio showing of the box: https://www.youtube.com/watch?v=LE5Cd3vMVSQ&t=1s

3D printing settings

My printer is a TENLOG Hands 2.
I used PLA, layer height of 0,2 and an infill of 10%.

I printed the lid with 25% infill. The lid must be very robust, otherwise it can break. Use as little support as possible so it does not break when removing the supports.
