HEPA Filter Case for Elegoo Centauri Carbon / Carbon2 – Magnetic Screwless Mount

HEPA Filter Case

for Elegoo Centauri Carbon / Carbon2 / Core One – Magnetic Screwless Mount

This is a clean, effective, and easy-to-print HEPA filter enclosure designed specifically for the Elegoo Centauri Carbon and Centauri Carbon2, while remaining fully compatible with any 3D printer that has a fan outlet up to 110 × 110 mm and a magnetic enclosure wall.

Key Features

• Holds up to 40 mm thick HEPA filter material (standard sheet sizes or DIY cut-to-fit from larger rolls)

• Hexagonal airflow grille on the outlet side for excellent airflow with minimal restriction

• Internal snap-in slots for two 40 × 20 × 5 mm magnets – completely screwless mounting

• Strong magnetic attachment to the printer’s enclosure (no tools, no drilling, no permanent modification)

• Compact, sturdy design that doesn’t block visibility or access

• Print-in-place, no supports required

What You Need

• Filament: PLA, PETG, or any standard material works great (PLA is more than sufficient)

• Magnets: 2× 40 × 20 × 5 mm neodymium magnets (very common and inexpensive)

• Filter media: Any HEPA filter material up to 40 mm thick. Pre-cut pads or larger sheets you can cut with scissors work perfectly.

Printing Instructions

• No supports needed – the model is optimized for easy printing

• 0.2 mm layer height recommended

• 15–20% infill is sufficient

• Print with your usual settings for functional parts

• Orientation: prints flat on the build plate as provided

(This one was printed with Geeetech PLA Silk Cooper,
a layer height of 0.32 mm and a nozzle wide of 0.8 mm.)

Assembly (5 minutes)

1. Print the cage.

2. Press the two 40×20×5 mm magnets into the internal snap-fit pockets.

3. Cut your HEPA filter material to fit snugly inside the cage.

4. Snap the outlet grille/cover in place to secure the filter.

5. Attach the whole assembly magnetically to your printer’s fan outlet. Done!

The filter can be removed and replaced in seconds whenever needed.

Compatibility

• Elegoo Centauri Carbon – perfect fit

• Elegoo Centauri Carbon2 – perfect fit

• Any other printer with a ≤ 110 × 110 mm fan outlet and magnetic enclosure panels

Ideal for reducing fine particles, VOCs, and odors during long prints, especially with materials like ABS, ASA, or nylon.

Print it, magnet it, breathe easier.

Feel free to remix or scale slightly if your fan outlet differs slightly. Happy printing and cleaner air! 🖨✨
