Idea of controlling chamber temperature by adding temperature-controlled exhaust vent

[Roberts_Clif]

I have a home made enclosure with a small heater and an InkBird thermostat. With the thermostat set at 100F the small heater and heated bed keep the enclosure at 100F without external venting. I put the sensor near my rambo board.. probably hotter up on the build platform.

I Too have a home Made enclosure, with a outdoor thermometer behind each 3D Printer and the temperature stays pretty close to 100F .
I do not have to do anything, however I have a bathroom vent with a light dimmer switch to vent smells outside.

Have not had any problems with venting the smelly air outside.
Here is a sample of an ABS Print.
