I created inverted pedals since for the fanatec csr pedals since I didn't want to buy the brackets sold by fanatec. The only problem with the design is that I miscalculated the opening where part of the pedal assembly will slide into by 4mm on the brake pedal bracket, and about 2 mm on the gas pedal. if you want to file it down a little it can slide in for an even more secure fit, but works just as well if you leave it as is. This is more of a prototype might update this in the future when i get the chance too. For infill id recommend 50-60% if you like smashing your foot down clutch kicking and what not for most rigidity and filament saving if you need so.Enjoy!
