Wallet credit card size two keys holder, adjustable

thingiverse

My [wallet has multiple compartments for cards](https://pvb.pp.ru/b.php?item=Wallet), of which I do not have too many as I have a few in my mobile. Occasionally, I keep forgetting my home key and postbox key (yes, there is a lot of paper post in Germany). Inspired by https://www.thingiverse.com/thing:2992263, I decided to create my own custom key holder for both keys. The size of the card is 80mm x 50mm (5mm smaller in width and 5mm smaller in height as compared to a regular credit card size) so it can fit easily in a wallet compartment given its thickness of 2.65mm (0.3mm back layer and 2.35mm the thickness of a larger key). You can adjust the sizes in "s" spreadsheet to your key sizes if necessary. Please use FreeCAD to open keycard.FCStd and adjust the sizes for your keys. Please refer to https://wiki.freecadweb.org/Spreadsheet_Workbench As you may have noticed, [my wallet](https://pvb.pp.ru/b.php?item=Wallet) has a large compartment for coins. Again, really useful detail here in Germany, e.g. to pay for a parking in the mountains in absence of a mobile coverage (cannot pay via a mobile app) or older parking machines accepting only coins, or to pay for an ice-cream or a bretzl, where a shop accepts only cash. As a result, my coin compartment tends to suffer from excessive coins and I tend to put excessive coins on a side. Now, I can use also my universal coin holder, which you can find at https://www.thingiverse.com/thing:5179598 And if you are an active Elegoo Mars Pro user, please consider my design of non-destructive exhaust system at https://www.thingiverse.com/thing:5179647
