Printer Enclosure Air Cleaner

I wanted a filter for ABS fumes and didn't find anything to my liking, so I designed this. It prints without supports and is modular so you can add or remove "cells" according to the size of your printer enclosure in 2 inch increments. The fan supports are sized for a specific fan, but the blower end is designed so that different fan mounts can be used if a different fan is used.

I haven't used it extensively, but it does move air from the enclosure through the carbon filters, so functionally it meets requirements. Whether its use is validated will be based on experience as I print ABS parts (usually I print PLA, so experience will be slow in accumulating).
