I designed a compact, elegant base for my Anycubic Photon S that integrates a replaceable carbon filter and tool storage. Most solutions I've seen online are these gigantic 4 inch diameter carbon filter units designed for much larger machines, and I wanted to make something specifically for our Photon S.

The design intent is for the first fan (mounted on top of the base) to sit flush with the underside of the Photon S, pulling air down into the carbon filter. The second fan assists by continuing to pull air out of the carbon filter and out the back. The carbon filter can be easily swapped out for a fresh one (if you print more than one), and they are easy to refill/refresh with new carbon media. So far I've printed about 3.5L worth of resin and haven't had to change the filter yet.

The base includes screw holes for M3 screws, wire management/channels for both fans to go down and into the base, and symmetrical cutouts for the power wire (depending if you want it to come out the left or right side).

 It will require:

• Two 80mm fans
• Activated carbon (charcoal) granules
• 3D printer capable of printing 200mm x 180mm x 100mm
• A round rocker switch fit for a 20mm hole
• Your own power supply and wiring for the fans
• Fine wire mesh (2-9/16in or 2-1/2in diameter)

I purchased my activated carbon from McMaster-Carr (https://www.mcmaster.com/3190k288), as well as my fine wire mesh (https://www.mcmaster.com/2930t58). I'll post more resources for this if it gets popular and if others have suggestions.

1. The base, carbon filter frame, and carbon filter mesh guides all need to be 3D printed. I have NOT provided support for these parts. For what it's worth, I printed it at a 45 degree angle with one of the beveled edges flat on the bed, with minimal support, and it was about 5 hours quicker than printing it flat. 

2. Video guide: (https://www.youtube.com/watch?v=i0mp4c9jrKY) To fill the carbon filter frame, you must alternate layers of wire mesh and filter guides, adding just enough carbon granules into the cells to fill it up over halfway. You can also put in two filter guides for every wire mesh, which I believe the video shows me doing.

3. Wire up the fans and install correctly. The top fan pulls air down, the back fan pulls air out.

4. My power adapter was a 19V source, so I had to wire in a buck converter to lower it to 12V, but do what works for your situation.

Please note that the small fan at the back of the Photon S will need to be either reversed, or you can disable it and cover it up. I reversed mine so that it pulls air into the unit.

If you have any questions or suggestions, I'm always open to it!
