DO THIS MOD AT YOUR OWN RISK
Based on Roger's Begode EX30 tire spacer, I upscale said spacers to fit the Master Pro rim size (17 inches rim). This is meant for Master Pro V3, in order to make the C40 motor more nimble and require less effort to turn.
What it is: The C40 motor have abnormal width, and stretches the tire mounted to it and ruin the profile of the tire, which makes it flatter and harder to turn with. These spacers fits between the rim and tire sidewall to squeeze the tire inward and give it a pointier profile.
Material: Hard TPU (95A-98A), do not use normal Duramic or Overture TPU, they are too soft. Any cheap brand TPU should do the job, I recommend Priline, Giantarm or Geeeetech. I don't recommend using anything that's not TPU, have seen cases of the spacers breaking inside.
Nozzle: 0.6mm nozzle and bigger.
Print settings: All walls (perimeters), 100% infill, just put 20 walls in your slicer settings.
