Perfect Poor Man's Printer / VOC Fume Extractor

NEWS! This is now confirmed to work with the Core 300 series filters!

If you’re printing ABS, ASA, Nylon, or other high-VOC materials, room air purifiers and open enclosures aren’t enough.

This model is a sealed fume extractor shroud designed specifically for the realtively-cheap and easy-to-automate Core 200S air filter and Core 300 air filters (thanks to @oldIT for confirming!) , creating a controlled airflow path that actively pulls fumes from the printer, forces them through filtration matrix, and exhausts filtered air out the top.

Why spend $500+ for the Bambu filtration system when you can have a similar system for <$100 ?

For the Core 200S users, this design pairs intentionally with my Core 200S carbon filter insert, forming a complete VOC mitigation system rather than just passive HEPA filtration. Instead of hoping fumes eventually reach a purifier, this system captures them at the source. This system is designed to be compatible with the hose fittings from the incredible Quicklock system from Made.in.Meidling.

Key design goals:

• Sealed airflow path (no bypass leaks), but also easily able to be opened to allow or whole-room filtration. To provide ventilation for the room, you simply have to slide the top portion of the housing upwards to allow air into the lower housing.
• High static-pressure compatibility
• Directional exhaust away from the printer
• Print-friendly geometry with no exotic hardware

This is a functional, no-nonsense solution for anyone printing indoors who actually cares about air quality.

🔧 Features:

• Designed for Core 200S HEPA filter systems (reportedly works with Core 300S as well!)
• Fully sealed shroud to prevent air bypass
• Active fume extraction with negative pressure directly from the printer
• Top exhaust to promote vertical airflow
• Complements carbon filter insert for true VOC removal
• No electronics or firmware required

🧠 Why This Matters:

Many “3D printer air solutions” just move air around the room.

This system:

• Captures fumes before they spread
• Forces air through carbon media
• Reduces VOC exposure instead of diluting it

If you print indoors, this is one of the most meaningful upgrades you can make to keep your workspace healthy.
