Super Mario Question Box

For all the nerds out there, I made a Super Mario question mark box to hide your secrets ;-).
The box can be locked by two hidden sliders.

For the best result, you should print it in three colors. All parts can be printed without support.

Outer dimensions: 150mm x 150mm x 150mm
Inner dimensions: 134mm x 134mm x 134mm

Have fun with it :-)
