Wanhao i3 plus y-belt pulley mount

Replacement/upgrade part for the y-belt idler pulley on the wanhao i3 plus. I found the original idler to be inefficient, as it struggles to cope with the belt tension and gets missaligned to a point where it is damaging the belt.

The part is a drop-in replacement. It uses the original screws and mounting points. There are also two additional, optional threads to further enhance rigidity. To use these, you have to drill some 3mm holes in your printer base and get additional screws.
