ok So like normal I started with a part off here and ended up not happy with it in the long run so I searched again and found the one I used to remix for this. Fits a TFT28 can be mounted about anywhere. I started with the design listed in the remix (not the first one I used) then I removed the screws from the front as I didn't see a need for them if I could put them in from the back... than I went ahead and added a sd card and USB thumb drive holder to the top. I also removed all the extra openings on the back that I would not be using I also added the Tronxy name to the front cover as well as the X3. I guess if you want it would be simple enough to remove those. I also left space above the Tronxy to allow for other things to be added to customize it to your own liking.
Update: sept. 19, 17 updated the back because when I printed I noticed it was connected but not as good as I would like as it would be easy to tip backwards and break it off.
