SO this is my design 100%. I drew this in tinker to make a cover for my primary chain converion that I did . Just wanted it to keep the major debris outta my chain drive area and prevent my boot from getting in there and rubbing on the nut while riding. Its nothing to fancy, but its functional.

I could have used the OEM one im sure but I wanted it to be open so debris didnt build up in there. Kinda like self emptying or atleast easier to wash out when I needed to.

Maybe it will be useful to others! Enjoy!
