About this 3D model

I designed it as a joke for my family, I have this printer and everybody ask me to print everything since the toner is cheap, but nobody gives me money to buy ink or paper. Print the lateral panels with white or gray, the middle body with black. I glued the left panel and screwed in the right one with 2 M3 screw (I put M3 inserts on the body). It can hold about 3 kg of coins.
