I made a mount for my Fanatec CSL Elite Pedals, where I can adjust the angle, while mounted to a wooden base.
Stuff I used:
The front and back inner spacing is roughly 19.7 cm, best way to mark it is to loosen the outer M8 screws and flatten all 4 sides at 0° angle, then you can mark the outside of the front and back mounting points.
I printed everything in standard PLA with Prusaslicer defaults (2 perimiters, 20% infill, 5 top and 4 bottom solid layers), with my Prusa Mini. With it I was able to use the 95 shore rubbers on the load cell brake pedal with full force (If I recall correctly they required a brake force of 90kg), which I used for some time and replaced it now with some springs, for a better feel.
The author marked this model as their own original creation.
