SainSmart Smart Controller LCD 12864 Case

I had printed another design, but found that it was a bit lacking and so I felt like it was time to make my own.

This design is screwless, and the display assembly should sit on the rear posts with the top clamping on afterward, with no issues even at a low print quality. I did not leave any openings for the contrast and backlight adjustment pots, so you should be sure to adjust those before installation.Two buttons are on the front of the display, marked with S for stop and L for light, and they should be able to flex enough to hit the buttons on the control PCB.
