Sovol SV08 Z Belt Tensioner - Fix

This is a remix of Nadir's z-belt tensioner.  With his model, the side screw doesn't work, because the plastic is too thick where it touches the metal of the printer.  This mod cuts that plastic so it fits snuggly against the metal tab.  I also thickened the plastic around that cut so it would hold strongly.

This remix is based on a slightly older version of Nadir's model.  I thought he had fixed this problem, but was happy with my version so hadn't downloaded or tried his latest.  It has been working great for me over the past few months.  Hopefully, someone finds it useful.  Please make sure to follow the original model's instructions for printing/using.

This cuts out a notch so that it connects correctly with the metal tab on the printer.  I also then reinforced that section because of the plastic that had to be removed.  This is a modification of a slightly older version of Nadir's model.
