Super Mario Question Mark Box Piggy Bank Coin Box

Here we have a coin case / piggy bank, designed after the well-known question mark block known from several Super Mario games. 

This box prints as a single piece without supports, if you don't count the white parts. The inner top part up to the coin slot is modeled at an angle, which is why no support is needed. The lower part features a hole and cap to get your money out again if you need to.

Assembly: The question mark should fit as it, it's a very tight fit, no glue needed. For the pins (if you decide you want them): they should be a millimeter smaller than the holes so you have a bit of leeway.

I did not like the existing models, that's why I designed this one myself. You can find the STLs here too. Enjoy!
