About this 3D model

Inspired by the BentoMini, I wanted something that was more powerful and capable of meeting several functions at the same time. I searched out a more powerful fan that did not rely on the housing/ducting. I also see that a Aux Fan cooling, VOC filtration and chamber heating are almost always mutually exclusive. So why can't this be done with one fan and selective dampers. This is where BentoXL was born.
