Functioning 3D printed Maneki Neko

This is a working Maneki Neko. The Maniki Neko is a lucky charm in Asia. Everyone knows it, but no one thinks about how it works. On the Internet you can hardly find anything about the function. The principle of operation is simple and ingenious. This is something unique and has never been published on the Internet.
I wound copper coils and did some testing. The electrical board consists of very few parts. Anyone who can use a soldering machine should be able to do it. The only thing that is a bit tricky is winding the coil. I wound it from 0,05mm copper wire. It takes a few tries but with a little practice it is no problem.
In a few days, an accurate construction manual will appear on my YouTube channel

It was printed with 0.2mm layer height. No supports are needed.
