Spinning Spring Top

myminifactory

This is a fun Pull Top I designed that while spinning will deploy 3 fins. These fins will retract as it slows and will fully retract automatically when stopped. This is a really fun toy for kids since it is easy to spin with the pull launcher and is really fun to watch. This top uses an inner spring to keep the Fins inside the top until centripital force from spinning pulls them out. All parts are 3D printed and only Superglue is needed for assembly!
