The driving wheels of McCulloch lawn mowers wear down. Rather than buying new wheels, I tried printing a new shell to put on top of the worn down driving wheel. There are 3 different sizes, pick the one according to how worn down your wheel is. For me, the 192mm version worked best (press fitted, printed in DasFilament PETG)
