numbered piggy bank / money box / collection

A numbered piggy bank collection. 2 versions:

• rounded 
• square

3 versions. 1000, 1500, 2000. The numbers can be filled in with a fine liner. The models exist out of two components. A box and a cap. This is for easy printing and no waist. Walls are thin to save filament, but strong enough. If you have any improvement ideas, let me know!
