Fidget Gears for School Math. Basic calculation 2 to 9

I did these for my wifes school class. 

Printed them in PLA with a layerchange for the last 2 layers, for the numbers.

it depends a little on the filament but with the blue one there were loose at once. The tricolour was a little tighter. But it was very easy to “breake” it loose.  Some spinning and some drops of “balistol-oil” and they spinn very nice.
