Nut and Bolt Coin Bank

This model is for a child's coin bank. Coins are dropped in the slot on top. The nut screws off to expose an access hole to remove the coins. The 80mm wrench fits the bolt and nut and is fun for the kids but not required or recommended for use to remove the nut. This can also be used as a coordination development toy for the kiddos. 
 

The bank measures 80mm wide (3.15") and 105 mm (4.1") tall and can hold lots of coins. I printed with PLA with a 0.16mm layer height and a wall count of 3 for the nut and bolt. The wrench I had a 0.2mm layer height.  I was able to print all without supports however the round vertical opening in the bolt printed better with a support using a angular threshold for high angles (75 degrees in Cura, low angles or 15 degrees in Bambu/Prusa). Enjoy!
