Dollar coin wallet holder (parametric)
by dylanwinn, published
This thing allows you to carry up to six US dollar coins in the space of a couple of cards, for example in an unused space in your wallet. No more jingling pockets! The holes are tapered so that the coins easily slide into the top but will not fall out the bottom. You can modify the design to fit other coins by changing the measurements at the top of the scad file.
