You could use that along with some aluminum tape to seal it to the back of the cutter.

I use this blower: attwood Quiet Blower Water Resistant (White, 4-Inch) https://www.amazon.com/dp/B003EX02DA/ref=cm_sw_r_cp_api_3L18BbTB6G1FB

Along with this vent hose: White Flexible Pvc Vinyl Vent Duct Hose, 4 in. x 20 ft. https://www.amazon.com/dp/B01G198P5A/ref=cm_sw_r_cp_api_4R18BbNJ19ANP

These clamps: Cambridge Tension Clamps, 2 Pk, Zinc Plated Steel https://www.amazon.com/dp/B07737XRRH/ref=cm_sw_r_cp_api_SS18Bb12827MZ

And this quick disconnect: Dryer Dock Dryer Vent 6" for 4" Tubes, White https://www.amazon.com/dp/B0028BAAWW/ref=cm_sw_r_cp_api_4T18BbV6CJ1TW

If you put the blower near the window it will keep negative pressure upstream which helps put less smoke into the room.

I don’t exhaust out a window, but something like this might do the trick for you: Window Dryer Vent (Adjusts 24 Inch Through 36 Inch) by Vent Works https://www.amazon.com/dp/B01M17V4CO/ref=cm_sw_r_cp_api_AW18BbDW0592D Though there may be cheaper or better DIY options for that part.
