I love his design. Thanks for doing it! I do agree with some of the comments. I need countersunk holes, especially since I am using a different x carriage than most people and I must insert the screws from the front. Also, It would be nice if this design didn't stick out from the extruder motor those extra 4mm. My hobbed gear set screw is totally stripped so I can't move it and therefore I cannot use this design at all. I am using lawsy's MK5 for now.
