When I put my shaft through the vehicle body (small robot) and have the motor attached to it through two rotating gears, the shaft isn’t rotating?

I think it’s due to how the hole diameter is the same as the shaft diameter? Do I need to put a component in between the hole and shaft to allow rotation please?

Thank you

  • $\begingroup$ if the hole is the same diameter as the shaft, then how could you insert something between the hole and the shaft? ... has it not occured to you to make the hole slightly larger? $\endgroup$ – jsotola Feb 1 at 19:42
