The model is done in Openscad, and can be parametrized to pretty much any dimensions.

It also includes the option “closed top” for creating a cover, and inserts for smaller coins.

The stl-files are sized to house a 1oz silver “wiener philharmoniker” or a 1oz silver “maple leaf”, as well as a fitting Top and two inserts for smaller coins (1/2oz and 1/25oz)

The Library used for the threads is specified in the scad file.

Also added a litte fuzzy skin in prusaslicer for more grip.
