Twist Axis for Thrustmaster/Virpil

Press Like for encouragement. Comment for improvement.

Twist axis for Thrustmaster Cougar/Warthog and Virpil sticks.

This model has been designed on request. I did not print it myself nor tested it.

You'll need:

• a rotary potentiometer “RK097N”. Resistance doesn't matter, because of the calibration later.
• 2x 6mm x 20mm (or longer) compression spring.
• 20x 4mm (diameter) bearing balls. (I got mine out of a bike).

1. Place the upper part on the lower part so that the channel is aligned with the hole in the bearing race. (→ see first picture, ball bearing in red)
2. Insert the bearing balls into the channel.
3. Center the upper and lower parts
4. Add the gear
5. Insert the potentiometer and glue or bolt it, if needed.
    

Disclaimer:
Plastic isn't as resilient as the metal of the grip.
Consider resin. If it's not an option, don't be cheap on the plastic. Use PLA or stronger, go 100% infill and print with an angle (potential crack to filament layer). Adapt the joystick response curves so you don't yank your stick like a mad man. Then it'll be fine.
