This enclosure requires you to 3D print some parts and cut some 8mm plastic sheets then assemble. If you don't have access to a 3D printer, people within the community are willing to help. If you don't have access to a laser cutter, you can cut the plastic/wooden sheets by sawing with a jigsaw.
Here are the instructions which include a list of parts and a comprehensive guide. We also include here the STLs for 3D printing, and DXFs for laser cutting packed in ZIP files:
All the parts included with the camera.
First sand down the outer walls of the tower to flatten the surface.
Take a sealing lacquer and cover the outer surfaces in 3-4 steps - always sanding between the steps.
Finally use a lacquer spray to give it a nice finish.
Fixed with 3 screws and nuts
Make sure, no water can ingress here!
The rubber strips, that come with the fan, are great for fixing all together.
ATX-PSU 350W powers all electronics with 5V and 12V with sufficient power for future sensors.
The Nano is mounted on the foundation.
The Noctua fan is mounted on top of the cooling ribs and the vent is fixed to the fan.
The air intake (right front) is covered with gauze, that is kept in place by a rubber band.
Behind is the 5-port switch.
