Air purifier for SLA printers

Air purifier for SLA printers. Circulates the air inside of the SLA printer hood, with carbon filter to absorb the resin fumes generated during printing.

You need:

• 40mm 5v fan.
• Thin carbon filter. I used cuttable Sini vacuum cleaner odor absorbant, that is available in Finland. Its 1mm thick. I used two layers.
• 4 X AA battery pack.
• 4 X AA batteries. I use rechargeable batteries.
• Optional: 40mm Laminar Flow Fan plate https://www.thingiverse.com/thing:432630

The bottom part is hold only by friction and battery pack has some weight. In the future I will refine the part by making claws that connect to the sides of the middle part. But for now hold it from the bottom.

I use this in Elegoo Mars 2 Pro.
