The author remixed this model.
this remix contains a servo controlled air dampener as well as the eletronics from the stealthmax (2x environmental sensors,2x VOC sensors).
the dampeners each use 2x 625-2RS Ball Bearings:

I have made 3 versions of the pinion gear for the servo, you need to choose the one that fits the best. (im using the medium one.)
