Grinderino 20x20 m2 adapter plate

myminifactory

I'm running a 20x20 stack but my stack holes are m2 and the wont fit the m3 hardware that comes with the griderino. My m2 stack screws weren't long enough either. This adapter plate has protrusions on the bottom that fit into the holes that the m3 press nuts would go in. The stack screw go in from the bottom, then the plate presses in place and is secured with the 25x25 holes. The plate keeps the stack from being able to shift laterally and the top plate fits flush holding the stack captive.
