Tevo Tornado Bed Leveling Knob

I found some nice looking knob design from Tevo's online store and quite liked them. unfortunately, it's only available shipping in China, so i decided to mock up my own.

i incorporated the 0.8 pitch concept, inspired by 3Dwinther's design https://www.thingiverse.com/thing:3006999

and i made the numbers go clockwise, so as the numbers increase, the gap between the bed and nozzle increases.

I ended up using a 0.5mm marker to highlight the outline of the numbers, so it's more readable.
