Ventilation duct for Ender 3

thingiverse

I Designed a custom ventilation duct for my Ender 3 3D printer as a protective cover for its control fan. Typically, the air is drawn in from above and can easily enter the enclosure, causing problems. The channel is secured on the front side with a small magnet (about 8mm x 3mm). In the back, I attached the ventilation duct using a clamp. To prevent dirt and debris from entering, I placed a thin fabric filter between the housing and the lid, which can be clamped into the intake opening. A sealant was applied to the lid to complete the connection to the control enclosure.
