This model was inspired by https://makerworld.com/en/models/443125#profileId-349172, but it also supports countries with thinner coins than the euros (such as Switzerland), where it wouldn't work otherwise (the model is 21mm high).

This has been made completely from scratch with Shapr3D and you can find the .shapr file along with a .step file in the raw downloads, in case you'd like to modify/remix it.

I have printed this with PLA, PETG and PETG-CF. They all seem to work quite fine, but if you're worried about it breaking, PETG would probably work best, since it bends easier than PLA.
