TEVO Bed level knob

This is a parametric bed level knob for TEVO printers (Tarantula and Black Widow), especially for 2016 models.
The knob has two holes, one for the provided metallic knob which has a diameter of 11mm, the other one for the screw that comes out from the bottom.
The knob should fit tightly into your metallic knob, although you can apply some glue if you wish.
I recommend printing a single one to test if you printer is giving the exact measures, and if not customize this accordingly changing the first hole diameter (11mm).
