I didn't want to spend 100+ dollars for a box with a fan when I knew I could make one 100 times better and share it with others!

What you will need:

• 120mm Blower Fan
• 2.5" Extendable Hose
• M5 Screws for the Top shell
• M4 Screws and bolts for the Middle and Bottom Shell
• Carbon Filter
• Lights (Optional)

This whole build assuming you already have the basics like the screws should only cost around 35 dollars. Way cheaper than buying a crappy box fan on Amazon…

Instructions:

I will post a tutorial on how to put this together but It's pretty straightforward.

1. Attach the Bottom shell and Middle plate using M4 Screws (Any length pretty much works)
2. Screw and bolt down the Blower fan.
3. Cut a square piece of carbon filter to place onto the top of the blower fan. (I used M4 bolts and just lid them into the empty holes on top of the blower fan)
4. Feed the wire through the large hole in the bottom.
5. Slide the exhaust pipe through into the fan. Can be kinda tough. (It can be easier doing this before mounting the fan.
6. Bolt-on the hose adapter to the top piece.
7. Then place the top piece onto the middle plate and use M5 bolts to go through the side holes.
8. Screw the hose onto the adapter and you are pretty much done.
9. The Feet are optional but I think it makes it look cool and helps with vibration. Also you won't scratch your desk if you are worried about that. I printed them with TPU.
10. If you want to add the lights I linked a 12v white led strip that I used. It's very bright and I just tied the wires into the fan wires and ran them up the hose.
