I looked for Hello Kitty money boxes on Makers World but couldn't find any, however there were some cool light boxes that inspired me.
I designed this from scratch as a money box.
No need for supports as I built some into the design and they snap off rather satisfyingly once printed (in the coin/note slot).
Prints in 3 bits:
The flower screws into the opening at the back so you can access the funds in the box.
