The current object is used for guide the LCD flat wire avoiding deforming it. I've increased the distance for Prusa MK3 aluminum profile width.
This part, can be assembled without dismount the MK3 frame structure. You only have to put the clip horizontally and turn 90º for secure it.

I've used the default Prusa PLA profile in Slic3r Prusa Edition
