The original design was fantastic, but I found I needed to make a few changes to work with what I had.
The Faceplate was modified to accept an SSD1306 128x32 OLED. I've found there are a bit easier and cheaper to acquire. It's a good fit that should stay in place, though a dab of hot glue wouldn't hurt. I also extended the mounting holes for the fan screws just a bit to better accommodate the hardware I had without trying to push through the front.
The Pi 3-4 Tray was modified to allow using M2.6 screws to mount the Pi to the base. I found the stubs in the original to be fragile and prone to popping off.
The author remixed this model.
Faceplate - remixed to fix SSD1306 128x32 OLED / Added a couple mm of depth to the fan screw holes to allow for what I had available.
RPi 3-4 Trey - reconfigured mount points to allow using M2.5 screws to attach Pi to base.
