This project is based on Airspeed Indicator of Cessna Skyhawk 172S.
You will need to complete this project:
- 1 step motor 28BYJ-48
- 1 axis of 3mm, I used a piece of telescopic antenna
For display you can print with Laser or Jet ink printer, I recomend to you apply a spray varnish before glue it.
I printed all parts with 0,15mm, 30% infill, no supports are required.
