Adapter to convert normal fan to duct fan

It is an adapter for changing the wind direction of the fan to wind up the acetone accumulated at the bottom when steaming the printed matter with ABS.

When I put 50 ml of acetone with a beckoning cat with a height of 18 cm and turned the fan for about 8 hours, it became smooth.
