Bullet Bill Bank Slot Insert

I've printed several 150% and 200% bullet bills and thought, man, it would be awesome to use the extra space at the bottom of the cap for something. Then the idea of turning it into a piggy bank came to me. I used tinkercad and modified the Red Insert part of the model to include a slot that would fit coins, even at 100%. This is modified to the Bullet Bill/Banzai Bill by Martin Moore from myminyfactory.

The slot is partly hidden by the bottom teeth.

I may try to shorten up the model a little bit for more room and less print time.
