Pin gear

I present to you a model of a pin gear, the model was created for printing on a 3D printer, the mechanism is tested and works great.
I don't know where to apply it, but on my channel this mechanism caused a lot of controversy, for which this model was made.
You can also watch the video where I talk about this program, collect and test.
