ADIMLab x-tensioner remix

I made this as a fun project to improve the x-tensioner. The bearing housing broke a couple times and the main bracket bent over time on the original, so I added some material to prevent that from happening. Also, the x belt was rubbing on the 2020 frame, so I lowered the profile and cut a groove for the bearing assembly. Tell me how this works for you, it's served me well so far.
