MathSpinner inspired me and I made a total re-design as a braille version.
I recomend to print the wheels with raft. Others as you like.
No support needed, except for the indicators on the screews.
By reducing the height of the axe you can adapt to the range of needed numbers. This needs some adaption in a slicing software as the screw theads need the given dimensions.
white wheels show digits 0-9
yellow wheels show operators (+ - / * = < >), units ($, €), and percent sign (%).
The blank wheels are intended for your own ideas. Just adjust the
all wheels print with circular mode, for bottom/top-layer (4+ layers), loops 4-5
digit grouping ring prints best with no raft + circular printing + vase mode
You may polish the braille dots with a plastic spoon.
