About this 3D model
This object was made in Tinkercad. https://www.tinkercad.com/things/gm6AG28kmKN Here is a little tinker toy to play with. Just a few gears. This is my attempt to get aquainted with tinkercad. I used a predefined shape generator for the gears and made the base from scratch. The whole assembly turned out to be pretty thin and small, so it's a little delicate but certainly works. I'll try for something more durable next attempt.
