I modified the original to move the M3 nut trap to the bottom so the thumbscrew could be mounted on the bottom of the assembly (my printer / Duplicator I3 has the screws going through the hotbed then through the Y plate then the nuts on the bottom). I also changed the radius so the part would not hit the front and back on my particular printer (the scad file can still be modified).
