Here are the STL files for the v6.0 accelerator pedal as requested.
I indicate that it’s in beta and I didn’t print them, and probably wouldn’t, mainly due to lack of time.
It looks exactly like the clutch pedal, without the modifications specific to the latter (cable clamp screw, cable stop, cable guide). Everything else is the same so I think it should be good. The shopping list is the same as for the clutch pedal (link here) except for an M5x35 screw (for cable clamping).
The 3D files are available on thingiverse. Please give us feedback in comments if there is any problem or if everything is good.
