Thrustmaster T3PA Pro Pedal Realistic Clutch Feel (Single Spring)

UPDATE: V3 Design is going to allow for better strength and better adjustability for the clutch biting point!

Printed in eSun PETG (all parts are, just different colours)

I bought these ^^^

You will need screws and I drilled out the holes to the size that I needed. No need to drill the M3 holes for where the spring attaches.

You can adjust the spring to adapt to your preferred clutch heaviness, and there are other mounting holes which you can use if you want, say if you want a linear feel for a brake pedal then experiment with the holes.
