I was tired of the limitations of the MKS TFT display so I wanted to get a standard LCD for access to the menus. I did not want to reinvent the wheel so I used this case from ZilDV .
Remove the MKS TFT from the QQ and install and assemble as per pictures.
Materials: 4 M3x10, 4 M3x30(depending on how thick your display ends up), 8 M3 Nuts(if you strip the plastic)
RepRapDiscount full graphic smart controller Display. Amazon US Link (This is the one I bought but it has the upside down connectors)
I designed tolerances for tapping the holes with a M3 tap, if your going to use nuts drill them out to 3mm.
Note for ZilDV case: The design is based on a version of the board that has a removable display. Most now are soldered to the board. I printed the middle section up to a height of 3.3mm and stopped the print, at that thickness it fit perfectly between the two PCB's and the case halfs.
Note for LCD: Some boards have the connectors installed upside down if the display does not work this is probably why. Easy fix, google it...
Orient parts as shown in pictures.
Support only for the long overhang as shown. Its hidden so it does not need to be too nice.
