I designed this model as a quick and easy way to give money to your kids/nephews/nieces and make it fun as well.

Model is designed to be printed at the same time, on a X1C/P1P/P1S (unsure about A1/A1 Mini). The Name text can be edited to say whatever you want, it's part of the ‘Objects’ section in Bambu Studio.

You can color or change the filament assignments in Studio as well, each bunny/egg/outline is changeable.

To assemble, super glue or 3d gloop on the bottom edge, which is offset from the bottom layer, attach the top to the bottom and either clamp or put some weight on it until it dries. It's designed to fit 1 bill inside (I haven't tried 2 or more), the crisper the bill, the easier it is to slide in.
