Description
Stop cold air hitting the build plate directly on your X2D. X2D Left Aux Fan 45° Deflector for the rescue!
Designed as part of my ongoing collection of practical Bambu Lab upgrades. Each model is conceived, printed, and endurance-tested on my own machines, refined through dozens of iterations to match real mechanical behavior.
Likes and Boosts feed the MakerWorld algorithm and keep new models coming.
If you want more validated, community-driven models, Follow along. Everything here is tested, refined, and proven. |
This model redirects the airflow from the left auxiliary fan without blocking it. The air is guided 45 degrees upward, spreading through the chamber instead of creating a cold spot on the bed. The result is a more even and predictable chamber temperature.
Why not simply change filament settings or modify the G-code? With materials typically printed without a heated chamber, such as PLA or PETG, the auxiliary fans are also used to regulate chamber temperature. Long prints with disabled aux fans can lead to excessive chamber temperatures and therefore heat creep and severe nozzle clogs.
Please note, as users are often confused:
The door hinge is on the left, the door handle is on the right.
This model is for the Aux Fan on the LEFT side.
THIS model does NOT fit on the RIGHT side.
For the RIGHT side you need this model: Right Chamber Fan Deflector ⧸ X2D, P2S No Warping
This is about consistency and reliability, not speed records. If your goal is a lightning fast benchy, this model is not for you. If you want stable prints and repeatable results, this should be your next print.
I suggest using PETG, ABS or ASA für this print. I used PLA only for the hero shot of the model.
Part #17 in my X2Design Journey.
