EVA 3 top_endstop_mgn12c Rebuilt

This is a narrower rebuilt of the  original Top End stop for EVA 3, side holes for screws, and his part of the frame, has been removed, making the part 3 mm. narrower in X axis, at same time the heat inserting nuts has been mounted from bottom to top, making them much safer, my recommendation is to use cyanoacrilate glue instead of heat, also four anchorages for cable zip ties have been added, instead of the two original ones.
