6in reducer for Central Machinery (HF) 8in Portable Ventilator, to 6in hose

Created this reducer to allow us to use 6 inch hose that we had on hand with the Central Machinery 8" Portable Ventilator fan from Harbor Freight. Makes for a hugely improved exhaust system on our co2 laser cutter. To use with the fan, remove the grill and hardware from the end, slide the reducer inside, then secure with self tapping screws.
