Parts printed and painted ( Red/black: Panel liner for the switch covers and chrome for the knobs), then hand-drilled the holes with 0,5mm . Set the switch covers with the superb pair of precision tweezers and glued them with Tamiya Extra Thin Cement.
It is important to mention, that I chose a bigger scale for these switches, by willingly leaving the scale discipline. I really love how these sharp details are working to the eye.
