Moen faucet handle

Our tub faucet that we have has the handle directly screwed into the faucet. The threads wore out and I cant find a decent replacement. This is tested and works awesome.

The print I am using is a version old. I felt the handle is very narrow once fitted, so I increased thickness of the handle before uploading it here. Therefore the 3d design you see might differ a little bit from the print, but all thats changed between the model uploaded and print is the handle, the core design is the same and its tested

I think the model of the faucet is Moen Magellan Deck Mounted Roman Tub Filler.
