The Bit Coin Bank is a 3D-printable coin bank designed to resemble 1/4” drive bits, scaled up 10x. It offers a functional and tool-inspired way to store spare change.

Features:

• Four Individual Banks – Each bank is modeled after a different bit style (Phillips, Slotted, Torx, Robertson). 
• Alternate Models Without Slots - If coins aren't your thing, alternate versions are provided.
• Secure Plug System – Each bank has a screw-on bottom plug.
• Modular Holder – A two- or three-position holder is available, designed to resemble standard bit holders.
• Simple and Functional Design – Inspired by real tools, making it a great addition to any workspace or garage.

Printing Details:

• No supports required
• Prints well in PLA, though other materials will likely print well
• Designed to print at 100% scale - the bank walls are four perimeters thick (at 0.4mm) and print without any infill. 

Other Notes:

• Compatible screws (untested): https://makerworld.com/en/models/1110482
• I'd be happy to create other bit types - just send me a note
• Printing the holder with a 0.6mm or 0.8mm nozzle should result in quicker print times - I didn't print any samples with these nozzles, however, so cannot say if they will print nicely or not
• While the holder is limited to 3 holes for the print bed on an A1, I have ways to generate longer models and have a variant that glues together. I'd be happy to upload files, but these will be untested prints.
• Not to be confused with BitCoin

A practical and unique way to store coins - with a design that tool enthusiasts will appreciate.
