Bộ lọc HEPA đơn giản (Simple HEPA filter)

Very simple recirculating fan mount that accepts GL-2103 HEPA filters which can be purchased very cheap on amazon.

Uses a 92mm case fan, sized to fit in a Creality K1 with no modifications. 4 M3x8 screws will thread into the freshly printed frame, do not overtighten. Filters twist lock on the opposite side. Use a drop of glue if needed to bond the frame to the base. A small piece of 3M automotive tape can help keep the cable out of the way in your enclosure.

Recommend PETG or better for thermal resistance due to how close it sits to the heat bed.

No supports needed, use standard slicer settings.
