Keep your enclosure's temperature optimal using this (manual) air trimmer.

Designed for a 64mm bore (press-fit).

I placed two holes in the enclosure: one directly under the build plate (to avoid side drafts) and one on the side near the top. By adjusting both trimmers you can regulate the temperature of the enclosure to the desired setpoint.
