Model origin

The author remixed this model.

Differences of the remix compared to the original

Intended for 4” dryer exhaust duct and inline fan to create negative pressure within the Core One chamber to discretly ventilate the harmful VOC and PM2.5 particles from inside living spaces. 

Does not negativly effect the chamber temp past 2-3 Degrees at max settings. Also is dependent on tempurature of living space environment. 

It is easy to install, and easy to print, no supports needed. 

PETG at minimum is reccomended. No adverse thermal effects from PETG and exhaust temp as it is well below warping temp for PETG as its between 70°C and 90°C and the air ventilated cant get hotter than 50C as per the hot bed limitations.
