You also need SOCKET HEAD screws for the stack (22mm maximum length). Not included in the kit.

Rivet holes might need some filing to fit properly, depends of the CNC tolerance.

Screws goes like this:

m3x6  x 10 (top + bottom plate)
m3x8  x 4  (xplate arm)
m3x10 x 1  (xplate center)
m3x12 x 4  (arm-standoff)
