What You'll Need:
1. The laser-cut parts of the case are protected by an adhesive film which needs to be removed before assembly (this is *very* therapeutic), simply peel it off. Now is also a good time to snap the light-pipes and holder out.
2. Using the screws, attach the smaller 5mm m/f stand-offs to the bottom plate of the case.
3. Place your Raspberry Pi 4 Model B on top of these stand-offs with the SD card above the SD cutout and attach the 12mm m/f standoffs.
4. Place your Cluster HAT on top of your Raspberry Pi, be very careful to line up the GPIO pins correctly so that they are not bent. Then add the 35mm f/f standoffs and slide the light-pipe holder into place.
5. Now you can add your Raspberry Pi Zero boards to the Cluster HAT.
6. The five smaller light-pipes dock inside each of the holes at the front of the holder, while the longer light-pipe sits in the gap further back. These pipes carry the light from the HATs LEDs to the front of the case where they can be easily seen.
7. Carefully slide the side pieces into position, the front light-pipes can make this a little fiddly but once it's done you won't need to adjust these again! You'll need to nudge each pipe into it's respective hole in the front panel.
3.Now drop the lid into place and secure with the remaining four screws. be careful not to over tighten.
Viola! Case complete!
