Laser engraver motor mount for Nema 17,23 using series 10, 80/20 extrusion

Changed the file to accept eigther Nema 17 or 23, I will be changing most plastic parts for aluminium plate and want to leave my options open for any future upgrades, this design is for extrusion type 80/20 series 10 and can not use the extrusion from the original design as I found out when first building it, the holes are 20mm apart which differ's from the original design but perfect for series 10 80/20 and the bolts used for the roller bearings were 5mm

we have now made a few mods to this
