LCD (20x4) Spacer

thingiverse

The LCD (20 characters by 4 rows) has been installed inside a robust alloy box. I required a spacer so the LCD frame would match perfectly with the exterior of the alloy box (2 mm thick) and also wanted to mount the LCD as discreetly as possible. By printing the spacer (complete with indentation for header pins) with holes for the LCD mounting holes, and chassis mounting holes that were outside the LCD PCB, I was able to use small self-tapping screws to first attach the LCD PCB to the spacer. I could then cut a precise aperture in the lid of the box for the LCD to protrude through. Because the chassis holes for the spacer mount were still accessible, I could then drill four small pilot holes for the mounting holes to mark their positions. These were then enlarged for the screws. This allowed the LCD to be mounted using only small screws and for the mounts also to be drilled easily. The project involves an Arduino Uno+GPS/SD card+Temp sensor to measure water temperature along a 22.8km lake.
