I'd gone from original, to the ones you've seen that you 3D print.This one blows them out of the water. The sturdiness of, particularly the x carriage version allows it to sit flush to tighten, with a huge amount of range to tension. Considerably more than you'll need.Blends right in with the rest of the printer, and takes away the continuous rubbing sound the belt makes on the edge of the original smooth bearing. I was so worried these would be garbage. They are excellent. Both the X and Y version.Just a bargain.
