This is a remix of the connector to mount the
ReprapDiscount Full Graphic Smart Controller Box in OpenSCAD by Professional3D to the top of a P3Steel frame. The part of interest it "P3 Steel Connector.stl". The files used to design it are also included.

I included a detailed drawing of the dimensions of the hole pattern. This will also give guidance on the length of the M3 screws needed to attach it.
