AC-27 Nozzle

Modified AC-27 air duster nozzle. The stock one has a wide opening that doesn't allow for much pressure. I bring it down to .500". That still allows a lot of air flow without losing a bunch to back pressure, which this device uses to cool itself. link to duster: https://www.amazon.com/dp/B0D878B2LK?ref=ppx_yo2ov_dt_b_fed_asin_title
