Spinning Wheel from Bike Parts - 3D Plans

I think this is the spinning wheel they built - or maybe a prototype?  

Looks like a walking wheel. I lived in Peru forty years ago and locals were starting to make and sell spinning wheels that were treadle operated from bicycle wheels. I would like to see a full treadle wheel made like this and I regret that I could not purchase one and bring it back with me.

I'm with Susan. I bought the last kickstarter bundle because I thought these plans were for a full spinning wheel, not a great wheel. I'm a little disappointed there aren't petals involved.

Perhaps I can create one? Anyone done that?
