Mega BBQ Heatermeter Fan

I currently have a couple of HeaterMeter devices that I built out and I wanted to have a more custom high volume fan housing for my 80mm. I intentionally was not looking to make this as small as possible, so just realize that this housing is not intended to be small. I live in Texas, things are big.

I designed it to be used with a 1" threaded pipe as a connector. What I have done in the past is purchased a 1" galvanized pipe. You can purchase whatever size you want. In order to get it to seat in my BBQ Guru Air inlet port, I used my grinder to grind off the threads of one end until it inserted snug into the fitting. Here is the link to my adapter. https://www.bbqguru.com/storenav?CategoryId=2&ProductId=14

When I design I try to achieve two main goals with all my builds - as few of supports needed, and snug/easy connection between the parts that don't require glue. In order to get the parts to fit together, I chose to build the fan housing as the one that requires supports
