About this 3D model

External measures are same as the original by kludgier (as you can see in the comparative picture), with M4 holes instead of M5 and reinforced with 1mm more height. I'm building the 1.5 version with M4 screws and PLA T-slot nuts (thing:32622) maybe in the future i'll adapt all the MM 1.5 design to fit better the M4 screws!
