Schrader valve air duster valve top

This valve top fits onto a Schrader valve to form a top similar to what is found on top of an Aerosol air duster, with the exception that this air duster can be easily refilled with a normal bicycle/car tyre pump.

This this youtube video I discuss how the model was designed, printed and used: http://youtu.be/pmN559MlUPg
