Display riser on aluminum extrusion for INFI-20 Belt Printer

I developed a riser that connects to the aluminum extrusions that will allow for the housing of the display and control board to properly cool.  The design from Sainsmart does not allow for proper cooling as the fan sits on top of the extrusions.  This issue can cause  the board to overheat which will require a replacement.  I mounted the new riser to the extrusion using 4 X T-slot nuts and 4 XM4*6 screws.  I reused the top mounting screws to connect the display to the riser, two M4 nuts where used to make sure the display was secure.
