The scroll wheel has broken for the second time in my lg magic controller. The price is high so I drew a replacement part. I printed from Pla and so far we are using 14 days and everything is in order. Of course, I recommend some other stronger material. I printed on chipboard 0.4 layer height 0.1mm and the model lying down with supports. It's a model without rubber, you can change it with the original controller.
