anet a8 y axis belt tensioner

Remix of a elfco's good design, I tried this print a few times in PLA and the parts snapped.
This version uses any standard M6 bolt (mine is circa 50mm long) and matching nut instead and includes an outer frame to protect the main body legs from spreading stress when tightened.

The overall length is longer giving more adjustment allowing you to use the original belt, Included is an optional point impact spreader for the bolt to avoid frame damage and spreading the load.
