Container with cap

thingiverse

Waterproof (maybe needs an o-ring) container designed specifically for bills and coins. The longer one is ideal for holding coins, accommodating a thickness of up to 2mm, while the bigger can fit larger coins measuring 27mm in diameter with a thickness of 3mm. The smallest version is perfect for storing emergency cash in your keychain, capable of holding a single folded and rolled bill. This design makes it easy to print without support, thanks to its simple structure. An open-source SCAD file is provided, allowing users to adjust parameters such as the maximum unsupported angle (ranging from 0° for vertical prints to 90° for horizontal prints) that their printer can handle. The cups and screw threads are designed to respect this angle, minimizing the need for bridging. However, a small bridge may be required for the cord hole, but most printers can handle this with ease. Users can also customize the cavity dimensions, thickness, and cord diameter to suit their needs. When printing at 0.3mm layer height, some force and patience may be necessary to screw in the first instance, but screws smoothly at 0.15mm layer height. This design utilizes Dan Kirshner's thread library for the screw, ensuring a secure and reliable fit.
