how-to build MACKRA a serb variant.

Step 2 Manufacturing: top plate.

this part is fairly simple, all you do is cut a peice of plexiglass to the same size as the base plate, and if you'de like you can cut a hole out in the center to make it easy to get to the electronics
also you should drill the four holes for the bolts to go through on each corner in the same place as you did on the base plate 
finnally drill a hole for where you would like the usb plug to come out
