Shapeways: Crank Contraption
The latest Un-set for Magic: the Gathering, called Unstable, introduces Contraptions as a new mechanic. Use this real life contraption to keep track of which of your contraption cards gets cranked each turn, by actually cranking the handle! These designs are all available my Shapeways Shop.
My Shapeways designs are 3D-printed in high quality steel, precious metals or, in some cases, colored nylon or sandstone. Most of them are available in a range of different finishes and/or colors.
