Backshell for 5" LCD Panel

thingiverse

Notice I need to move the four mounting holes on the rear of the backshell, as they interfere with the buttons.NEW Woops, almost forgot the button extenders! Print 5 of these; you might have to clean up the print a little; it's a tight fit. Also, I put a 1mm fillet on the outer edges and pushed the front and back side edges of the power socket opening. I also made a Desktop stand for 5" LCD panel frame that attaches to the back of the backshell.OLD This part goes with the front bezel for 5" LCD display that I made for a 5" HDMI (no touch) LCD panel I got from Adafruit (they list it as a Raspberry Pi accessory). This is the back. I put 50-mm holes for mounting; you can fashion an arm or desktop stand, if you wish; I'm going to either hunt one down or make one if it doesn't already exist, and link to it here if necessary. I'll have to include some assembly instructions. The wires on the button board are larger gauge and a bit longer than required, so I would like to replace them. I'm not 100% totally sure, but they look like JST PHR-series, and should work with 24AWG in these crimp-contacts from Digi-Key. Parts needed: 4 x 1/4" screws, (3) 2 x 1/4" countersink screws to attach the front panel. Thin craft foam (~1mm) Instructions I successfully test printed the backshell with the following: 3 shells, .2mm layers, 75% fill. Supports and raft on. Successful test printed the buttons as follows: 1 shell, .1mm layer, 100% fill, raft on (raft is crucial). The inner parts are held in with 5x #4 screws, 3 on the main board, 2 on the button board. The front bezel is held in place with 4x #2 flat-head screws. Use a short piece of plain PLA filament for the light pipe (Yes, the LED needs to be extended as well). I melted one end flat and wide enough to prevent its coming through the hole, then attached the button board and snipped the filament flat. Works like a charm! Well, almost. I used 1.75mm filament; a 3mm piece would be perfect.
