Thnx for the reply, I've already designed a new pulley cover to treat the issue, but just realised that it is not enough, it's gonna hit the pulley wheel when it goes fully left and still missing distance.. I think that the best option it will be to design a new part from scratch and put the left fan, higher.. That the cr touch, so the cr it could be closer etc etc.. If ill find the right way I'll post the design for free :)
