Note : i made this replacement for a destroyed knob so the shaft was destroyed too , and i was needed to file down the shaft to 5x3mm square! if you want to use this knob you will need to file down the plastic shaft to 5x3mm!

but if youre shaft is in good condition and you send me the measurements i can adapt the model to fit the original shaft as well and then you will be not needed to file down anything.

(in the dark photos the replaced knob is the one on the right side)
