I hollowed out the model so that it could be used as a piggy bank.
I made 4 different sizes for the 3 largest there is no need for support when printing, On the other hand for the smallest I had to change the opening mode and therefore it requires some support, I included it in the 3mf file.
The sizes of the models are:
Big : 186x124x156mm
Medium : 139x93x116mm
Small : 93x62x77mm
Mini : 61x41x51mm
The size of the openings are 40x3mm for the 3 largest models for the "mini" the opening is 28x3mm.
The author remixed this model.
