Model was created using references, then scaled to match size of real piggy bank (193 mm lenght, 56 mm width, 95 mm height). Coin hole was measured to be bigger than 5 pln coin (>24 mm diameter x 2 mm). Model in 2 formats: ready to slice and print STL, and original .blend. Whole model is single geometry, no separate parts, to avoid problems with some slicers.
