About this 3D model
I'm impatient, and lazy, so... Video of prototype is here: https://www.youtube.com/watch?v=fk1CsNBUk3o&list=UUv_zm49u-RjnCJVwhUO-ecA. Hand crank version is available. The finger cams are interchangeable with those of Impatience, so if you like the Impatience action, use those cams. Designed using Sketchup 8, and printed in PLA on a Makerbot Replicator 2 using Makerware 2.3.3.42.
