Re-Modeled with Blender.
The author remixed this model.
I just re-modelt the inner section using blender. just to make it stronger.
As well i widened the Slots in the nose a bit so that it's safe to scale it down.
→ x0.75 - Any usual coins should still fit. (Except ancient pirate gold coins)
→ x0.5 - still safe to print.
