Cub Scout Space Derby Winder

thingiverse

Faced with the possibility that my son would have to wind the propeller of his Cub Scout Space Derby rocket with his finger, I had to make a tool. This is it. Designed is AutoCAD to utilize a genuine Chinese TT motor that was purchased for $1.82 (including shipping) from Banggood. A momentary push button switch and 6 volts provided by four AA batteries makes it all work like a charm. It was a quick and utilitarian design, but if you would like to refine it, an IGES file is included so that you can modify the design in the parametric design/CADD application of your choosing. If you want any other tools designed, please feel free to contact me. Pack/Troop 423 can always use a donation :)
