SainSmart Smart Controller LCD 12864 Case

thingiverse

This case is specifically designed for the SainSmart LCD Smart Controller 12864, which adds a vital SD card slot and rotary control along with stop and backlight buttons to numerous 3D printer models. I had previously printed another design but found that it lacked certain features, so I felt it was time to create my own. This design is screwless, and the display assembly should sit on the rear posts with the top clamping in afterward, without any issues even at a low print quality. I intentionally left no openings for the contrast and backlight adjustment pots, so you must ensure to adjust those before installation. Two buttons are located 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. This initial version does not include a knob for the adjustment dial but I may add one in later revisions. I will also be uploading my original files once I've cleaned up the grouping and component names. As this case isn't designed for any specific mounting or fastener, I'll probably be adding an angled stand to it soon, at which point I will update this item. UPDATES: Modified design to provide stronger posts and looser tolerances on the sockets. (2/13/17) Print Settings Printer Brand: Printer: Robo 3D Rafts: Doesn't Matter Supports: No Resolution: Any Infill: Any Notes: This case should be able to be printed at any resolution, and printing at a full 0.3mm "low" resolution on my Robo3D R1 has resulted in a good print. My personal print is made with PETG, in order to have the flexibility required for the pushbuttons on the front of the case. How I Designed This Measurements To create this design, I found a CAD model of the SainSmart board by Ernesto Archundia which can be downloaded here and used it to calculate positions and spacing for the various components. His model was an excellent resource for the measurements while I couldn't find my digital calipers.
