Fix for Moen 90 Degree M-CORE 3-Series 2-Handle Shower Trim (UTS9011)
The Moen 90 Degree M-CORE 3-Series 2-Handle Shower Trim (UTS9011) seems to have a tolerance problem, causing the handle to turn independently of the hub, until the two contact each other.
I didn't want to just live with it that way, so I modeled up a shim that fits from behind, and fills the gaps to the left and right of the handle, to keep this from happening.
