Root 3 CNC - Upgrading the X-Axis 3mm Belt Mount

While looking through online sources, many people hand-cut a notch in the X-Axis 3mm Belt Mount in order to simplify belt-tightening.  Rather than cut into the exist part, measurements were taken from the provided STL file and a modified version was created.  The modified file can be found on Thingiverse.

Comparing the two parts:


The new part is on the left.  A notch has been added for the timing belt, as well as a few other minor changes.  All edges have been rounded, and the right side opening narrowed a bit to get the M3 screw holes a bit further from the edge.  The final part can be seen below.
