I put my Rostock to good use by trying to entertain my 17month old. I made him an airplane mobile for his room, but made it motorized using a hacked IKEA crank-powered flashlight.
Printed parts include the bearing mounting plate, rod holding clamps, counterweight mount, and crank extension.
Great idea! How about some blinking lights and maybe an enemy plane instead of washers as counter weight Fun stuff!

Thanks guys. Future plans may include a second plane at the other end, or maybe even a second plane on another bearing so they could race.
Lights are a good idea too that's easy to add
