LCD mount brackets - RepRapDiscount lcd panel on MendelMax2.0
These brackets screw onto the two horizontal extrusions running the length of the mendelmax 2.0
The small retaining clips hold the screen in place.
I know there are a number of LCD screens available, so make sure you check your dimensions before you try to use it. These clips hold a nominally 55mm wide, 1.6mm wide board, but have been designed to allow for some variation.
The clips mount off the top (or bottom) of 20mm extrusions at 50mm centres (vertically).
I mounted them using my twist-in nuts: http://www.thingiverse.com/thing:256124
