Spock's cooker knob

A replacement knob for cooker or else.
For a Neff cooker, but may work for others.

Inspired by Star Trek.

Printed using PLA, but ABS should work too.
The knobs do not melt as they are far enough from the hot area.
According to the printer settings and the material, scaling a little bit may be appropriate (1 or 2 %), but don't scale too much as it is required to be tightly attached.

Comments welcome.
