GT2560 To Arduino Mega Mounting Plate

After a slight conflagration incident, I was looking to replace my G2S Pro's Geeetech GT2560 control-board with an alternative. However doing so I didn't want to have to drill more holes in the printer, or be reduced to just gluing the Arduino/RAMPS/Stepper stack to the base.
Instead, here's an adaptor plate that uses the standoffs from a G2S (and probably any other printer using a GT2560) and gives you somewhere to mount an Arduino Mega and all the associated gubbins.
