Cessna C172S Airspeed Indicator

This is my first ever serious design. I am completely new to everything about this, including CAD, 3D Printing, and using a CNC machine. So as a disclaimer lots of things here might be inefficient or even completely useless, but since it ended up working for me, I decided to share it with other people.

I designed it to work specifically with the SG90 servo motor, and I used the Bambu P1S 3D printer to make essentially everything besides the glass layer. At the time of posting this, I still didn't make it, partly because I'm lazy, but I figured if you wanted to do it yourself you could use a CNC. It's entirely optional though, purely for aesthetics' and realism's sake, so basically you can use only a 3D printer to build this entire thing.

I also posted some screenshots of the design so you know how to assemble everything, although I should add some things. I used liquid glue for putting almost everything together, and that includes the calibrator knob, for which I applied glue on the
