Airbus A320 Audio Control Panel Reception Knob

Model for the 15 Reception audio level control knobs on the Airbus A320 ACP. Not a perfect replica as the real knobs are illuminated when released out and have a collar that fits into the panel, but for me, close enough.

Printed in matte black PLA, 100% infill. Marker line printed in white PLA or PETG, 100% infill, with 10 perimeters. Line is a push fit into knob, but can be glued in place with CA glue.

Designed for 11mm diameter hole in 3 x 3mm acrylic panel. Chamfer at base helps to centre knob when extended.

Knob designed to fit these ALPS extending potentiometers from AliExpress, which pop out when pressed and retract with second press. Outer band switch is easily removed and discarded. If anyone knows of a better extending potentiometer, let me know.
