Simple scroll wheel for Trust Fyda mouse, mine started acting weird because the hex was wearing out, so i tried to make a replacement one.

I suggest to print it cut in half to get the best accuracy possible for the rods, as they are quite small and doesn't allow much tolerance while mounting it back.

you will still need some supports for the ridges that keep the rubber in place, and some glue, but they should came out easily.

Enjoy
