This 3d Files is required for Turning Logitech Driving Force Gt Sim Raicing Wheel, Gear Drive To Belt Drive. 12 teeth Motor pulley should be ABS. The other parts can be PLA.

I also Aded 28ppr Encoder whell. 60 ppr encoder is cousing the reduce of degree of wheel rotation in games. Some games needs mor rotation degree like Euro Truck Simulator

For encoder wheel read Bellow

on cura(the slicer program) you should chose 0.3mm nozzle. If you are using 0,4mm Nozzle, it doesn't matter. Chose 0,3mm nozzle.And print quality must be 0,12mm.Also chose support types lines, and %10.Use ABS Filament if you can.pla is also good.İf you are going to use pla, maybe after long therm use, it can be getting softer and lose frım motor shaf. If that happens, after instalition encoder wheel to the motor shaft, put one drop super glue to the midele of wheel. Glue is going to hold them together.
