Nice, I printed one of these from the original https://www.thingiverse.com/thing:2786671 and it worked very well for my Mk3.
I'm now looking at doing a full bear upgrade or zaribo and looking for similar functionality. Think I'm leaning to the bear, but the x tensioner is not present, yet, and a V3 was recently mentioned.
Glad to find some of the bits I've been looking for. I also modified the MV part for my idler width (in Fusion360).
