Product Description
An educational toy to demonstrate a piston pump system driven by a windmill or hand crank.
The pump has cutaway sections so will not actually pump water.
Its designed to be printed already assembled.. no snap fitting, glueing etc.. (so as you would imagine, it will all be in one solid color.. not like in these renders) in case its not smooth enough to run on wind power, i've added a hand crank for manual operation.
