Throttle & mixture for flight sim

This a mostly realistic Cessna throttle and mixture for flight simulators. It connects to a PC similar to a joystick with a USB cable. The PCB used also allows for more buttons or pots, which could be added on the lid in the future.

These are all the models I remixed parts from:

### Assembly

Cut the 6 mm metal rod in two 166 mm pieces.
Glue the knobs on the rods like in the picture.

Solder one long ground wire and two short wires (5V and input) to the solder tabs of the potentiometer. Look at the picture for which wire goes where, black is ground, red is 5V and green is input.
Assemble the PotRodConnectors by placing a M3 nut in the hex shaped hole and secure it with a M3x12 screw. Do not screw them tight yet!
Stick one PotRodConnectorleft and one PotRodConnectorright on the potentiometers, so that the screw points inside. The back part with the screw should point to the two tabs of the potentiometer.
Screw two PotScrewPlates each on the potentiometers with the flat part outside.
Seat the potentiometers in the enclosure and secure them with 8 M3x6 screws. The side with the two contacts should point to the back.
Now screw in the mixture and throttle guide with the two printed nuts.
Finally, stick the throttle and mixture rod through all the way and fasten the screw on the potconnectors.
