Tevo Tornado Bed Leveling Knob

thingiverse

I came across some appealing knob designs at Tevo's online store that really caught my eye. Unfortunately, shipping is only available to China, so I decided to create my own mock-up instead. I incorporated the 0.8 pitch concept from 3Dwinther's design, which can be found on Thingiverse under ID: 3006999. To make it more user-friendly, I made the numbers go clockwise, increasing the gap between the bed and nozzle as the numbers increase. To enhance readability, I used a 0.5mm marker to highlight the outline of the numbers. While I'm not entirely satisfied with the result, I can live with it for now. I printed my mock-up using a 0.2 layer height and added support for areas touching the build plate, which helped achieve a nicer fit for the metal knobs. If you don't use support, you'll still get good results, as evident from my comparison prints – just be sure to cut out any hanging strings of PLA before installing your metal knobs. Keep in mind that my mock-up is specifically designed for the green Tevo model, and it fits snugly with the metal knobs. However, I'm unsure if the design has changed on later releases, such as the gold versions, so I can't guarantee a perfect fit.
