The LUDU (Lefthanded Urolig Dynamo Ultra) by deurolige6

Last crawled date: 4 years, 5 months ago

This is a 3D printed hand-held dynamo, which is operated by turning a handle which produces emitting light from the LED.
The word 'Urolig' is a danish word for 'restless' which has nothing to do with the specifications of this device.
