First of all, I think it's a great idea to use these gears to practice basic arithmetic in a fun way. Thank you very much to @Ckobar.
Especially when I want to print in multiple colors, I would like to have several STL files so that I can assign the objects to the colors. This was the original reason why I made a remix. I had also never designed gears in OpenSCAD before, so let's try.
In my version, there are 2 STL files for each spinner, one for the text and one for the fidget.
the numbers are rotated so that they are always the right way up when they are selected
The gears have a cone at the top and bottom so that you can't get your fingers caught in the teeth.
