## What it is
Nevermore Micro is an open-source hardware design for compact activated carbon air filters that remove VOCs and fumes from 3D printer enclosures. It provides printable parts, BOMs, and assembly instructions for single-fan (V4) and dual-fan (V5 Duo) variants.

## Use cases
- filter VOC fumes from a 3D printer enclosure
- reduce ABS printing smells in my workshop
- build a carbon filter for my Voron printer
- find printable air filter designs for resin or filament printing
- improve air quality around desktop 3D printers
- source acid-free activated carbon for a DIY filter

## When to choose
- you want an open-source, printable carbon filter for a 3D printer enclosure
- you need a compact filter that fits inside small printer builds
- you want community-proven BOMs and assembly guides for air filtration

## When to avoid
- you need a plug-and-play commercial air purifier
- you need HEPA-level particulate filtration rather than VOC/odor adsorption
- you have no access to a 3D printer to produce the parts

## Facets
- artifact type: application
- maturity: active
- function: simulation
- domain: hardware, developer-tools
- platform: cross-platform
- tags: 3d-printing, hardware-design, air-filtration, activated-carbon, voron, voc-filter, open-source-hardware
