Hi!

I've just finished my concentric rotary switch + encoder hybrid. It's enough small to fit EFIS or engine display control panel.

Project:

And ready module:

All parts are 3D-printed. It's possible to use different indexed rotary switches, but need replacement of gears (I have decided not to use 24-tooth gear as it's to small for 3D-printing).

Any opinions would be highly appreciated!
