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. not 100% happy with the result, but i guess i can live with them for now.

i used 0.2 layer height, and support for areas touching the build plate. This helps with a nicer fit for the metal knobs. you can probably live without support, as you can see from my comparison prints. you'll just need to cut out the hanging strings of PLA before fitting your metal ones in.

also, mine is a green Tevo, and the print is a tight fit with the metal knobs. i'm not sure if they changed the design on t
