The following is just a little trial of making a gearing in SOLIDWORKS. In doing so I've made a 'fidget disc', a form of spinning toy like a fidget spinner.
The following is renderings of the item:
Above is seen how it looks in it's acrylic shell. Below is how the gears are arranged inside it.
On the picture above is shown how the gears would move inside the fidget. it is ment to be hold with two fingeres holding on the central part of the middel gear. Note that the internal parts are all the same gear ratio. The entire assembly has a diameter of about 60 mm or 2.36 inches.
