Paramtric knob for metric nuts

This is a parametric knob for metric screws I created for some projects.

It is written in Openscad.

Attached is STL for M6, M8 and M10

Just edit the first variables to generate new knob design. If it is not on your liking you can thinker with the script to edit different diameters.

$bolt_size - the size of the bolt M6,M8,M10 etc

$knob_nr - this number defines how many groves the knob will have

$bolt_height - this is the height of the cavity for the bolt in mm

$knob_height - this is the height of the knob in mm
