Viktors Nyckel (spare key for piggybank)

thingiverse

In the winter, my son misplaced his piggy bank's key. I attempted to print a new one in January using ABS plastic but it was unsuccessful. Today, he requested another attempt, so I adjusted the size and used PLA on my 3D printer. Amazingly, the key opened the piggy bank's security system! Big win for us both, as we discovered his original key hidden inside too!
