3 Easydriver holder

I needed a fast way to hold 3 easydrives for the cnc I'm building and I added 4 more holes to attach them into another thing, like a piece of wood or metal.

6 x screws 2.5mm x 6mm tall (2 for each easydriver)
4 holes of ~4.5mm to attach the holder to something else

* Tested with easydrive v4.4
