This is a display case for a 20x4 i2c LCD display with a FT232h USB breakout board. With some basic programming you can use this to put notification messages from your computer on a separate display, or to display messages from a Pi or Arduino. There are holes to see the status lights of the FT-232h. I designed this as part of an ongoing robotics project I am working on, but it makes a great standalone feature so I thought I would post it.
I printed it with Hatchbox wood filament (215 nozzle, 30 bed). Picture shows it stained and glazed. I did not use supports, I printed it standing on end. The only reason I do the bed at 30 is for consistency in conditions every time I print.
I don't know why but I realized I made it so the USB is in upside down. It doesn't affect anything, but feel free to remix it.
Assembly: the end caps will be a tight fit at first but they will loosen up. Put the back two corners in and then the front corner should wedge itself in. Also, the display needs to be fed in from the right, flat against the back of the case, or the i2c board will not fit. Once the board is in, tilt the display to the standard angle, press the left side into the display opening, and then slide it to the left so it can fit around the jumper tracks of the FT-232h. If necessary, you can hot glue the FT-232h for more stability but I did not need to. Also, you can put the display in upside down and lay the case on the other side for a shallower angle.
