Small filter box for laser engraving.

Laser Engraving Filter BoxI designed and built a custom filter box that can holds up to 3 × Kenmore EF-2 86880 HEPA cartridges plus an activated charcoal filter at the end or where you want to place it inside the box. Added holes for brass threaded insert too.I use vacuum tubing 40mm. It also fits 40mm tubes. The idea came from needing a simple and affordable way to capture glass dust and fumes during UV laser engraving. It may also works well with CO₂ galvo engravers or other small desktop laser setups.3-stage HEPA setup catches fine glass particles and dustActivated charcoal stage helps reduce odors and VOCsUses easily available EF-2 86880 vacuum filtersModular design — filters can be swapped or stacked depending on the jobThis project is meant as a DIY air cleaning solution for makers working with materials that create fine dust and fumes. Safety Note: Glass dust and laser fumes can be hazardous. Always ensure proper ventilation, wear protective equipment when handling used filters,
