I'm proud to show off a quick hour design. I got fed up with coins and keys etc. lying around on my desk. Needed something to put my stuff. Not to big, not too small, just enough until i leave the house again.
I present to you a wallet, coin and key holder. Mountable with Tape. Alternatively the beveled cut should allow you to drill small mounting holes. It has space for a slim wallet, and thus don't expect a 100 euro note to fit too easily. As shown in the photos, if you're wallet is fatter, fold it and then drop it in. Coins work well, all euro coins work. Oh and there's a pen holder too!
Please post makes if you make one. I have included the Solid-works file for mixing and measurements fitting only.

This print will take a long time to print. For me it ran above 8 hours due to slow speeds of 50mm/s and beveled edges. You will need support, and a bit of post processing to remove said support for the coin holder bridge.
