Summary

A knob to replace one from a 2006 Mazda Demio.

Instructions

Print car_knob_demio2006_2.stl, then attach to the empty stick on your car. OpenSCAD files and source DXF files are provided as well for derivatives.

Version 2 includes a more substantial handle (without the flat circle base), so it feels like a more normal knob. The older version 1 is a flat cross, which is harder to turn.

Version 4 has a rounded outer part, similar to the original button (but angled at 45Â° instead of a gentle curve), and has been scadified to be almost fully parametric.
