These things are going extinct. The manufacturer in China is apparently discontinuing them, which is going to suck for a lot of CUV owners over time. We just sent out of our very last one.
I'm not sure what the original plastic rollers were made out of, but they sell frequently so they must not be the best material. I'm thinking of machining ours out of Acetal / Delrin, which should extend the life of the roller significantly.

Also, the original steel tensioner bodies seem to bend over time with use. We'll put the usual HD touch on that and thicken it up.
This post is a bookmark for now, I'll put together a 3D model and will upload it here later.
