HEPA+ActiveCarbon filter for printer housing based on IKEA PLATSA

thingiverse

To minimize odors and filter out nanoparticles produced when printing, I've designed a custom enclosure for my Creality Ender 3 Pro based on IKEA PLATSA. The housing measures 120x60x60 inches with two 60-inch doors - one featuring a window. The back panel of the IKEA PLATSA is 1/8 inch thick. I printed the fan grille and holder separately, ensuring each part has threaded connections for easy assembly. Initially, I experimented with a 92mm hole and a 1500rpm fan but found the airflow insufficient. Switching to a 3500rpm fan resulted in excessive back pressure, so I enlarged the hole to 120mm and revised the parts to accommodate the faster fan. I created two designs: one with a 50mm tube to reduce back pressure when the housing is positioned near a wall. I also designed an air filter system utilizing a Kärcher HEPA13-Filter and a 120mm fan running at 3500rpm (10W). Power supply was achieved using an LM2596S module. Later, I discovered that the Kärcher HEPA Filter wasn't properly oriented due to its reference stabilizer parts not aligning with 0°. Despite this, it functions correctly and merely appears off-center. UPDATE: In December 2019, I added an activated carbon filter (5x5 inches thick) to further enhance airflow quality.
