6mm offset belt clamp with striker for Makergear M2 with V4 Dual Extruder

When you get the dual extruder kit for the Makergear M2 you replace the X axis belt clamp. The stock design gives you a X home position which is about 5mm off the left side of the bed. I took the stock design and extended it by 6mm so X home should now be at the left edge of the bed making it easier to use the full area of the bed. Note, this was originally 5mm, but after installing it I think that 6mm would be slightly better, so I updated the file - yes this is me being picky.
