this is basically a just another piggy bank in form of a kind of future-ish crate. Should fit any coins, i guess - just tried Euros so far, but the slit is quite big.
The fit between top and bottom is fine in my case. However, this can change from printer to printer. Please keep in mind that i can't change it at the moment.
I recommend to print the top in upright position and underpin it with a gridlike support structure.
