About this 3D model
My brother-in-law – Philip Robbins – sketched out this idea for a coin holder to hold four pound coins and a fifty pence piece to go with his minimalist wallet by the [Machine Era Co](http://www.machine-era.com/collections/frontpage/products/the-machine-era-wallet-gunmetal-edition). After a few prints to get the size of the holes just right the final thing rolled off the Makerbot printed in Faberdashery white. Works pretty well.
