3D model of johann517. The models were repaired and checked for printability.
This is an electrostatic motor and generator combi device
The generator is known as
...さらに表示 Wommelsdorf (look it up e.g. US1071196) but extended with a dual inductor array (bunch of parallel wires), the motor is standard Poggendorf principle.
The voltage levels and jolts are quite nasty and i will not release the files at current stage. I guess i could also scale it down to a more human printable toy size thing.
