Airbus A320 Rudder Trim Knob - V2

Three part design that can be printed and used without any painting or post processing. Designed to be backlit for illuminated marker line

Main switch body printed in matte grey PLA, though can be printed in any colour and painted

Light Pipe printed in white PLA (or PETG) or transparent PETG if backlit marker line is required. 

Black line surrounds printed in matte black PLA.  Model is a pair that need to be split and laid flat for printing 

Hole diameter is 6.2mm for 6mm shaft. Threaded hole is for M3 5-10mm grub screw to secure shaft 

V2 - Subtle improvements to make marker line thinner and to make more accurate to the dimensions of real knob in actual aircraft.

Optimized for printing with a 0.2mm nozzle, (0.06mm layer height) but perfectly functional if printed with 0.4mm nozzle (0.15mm layer height). Body, Light Pipe and lines 100% infill. Marker lines print smoothest with 10 or more perimeters. 

Both STL and STEP files included.

Can be used in combination with Rotary Switch or with my rudder trim switch mechanism:
