This wallet is even easier to make if you have access to a laser cutter. You can also manually cut out too if you’re careful. I used 1.2 - 1.6mm Natural Veg Tan Cowhide. This can be dyed different colours if you want to experiment.
Having previously owned a bulky ‘traditional’ wallet for years, this compact design is much nicer to carry around. It can hold 5-8 cards and some coins, if you still use them…
There is a bounding box (the inner one) which you can use to scale the DXF correctly, it should be 400 x 280mm
If you want to fit more in the wallet, you can tweak the location of the holes for the snap fasteners
Make a cardboard or paper version first if you want to test the size!
