12CM*12CM Fan to ⌀80 Exhaust Duct Intake Adapter Hood

Description
The model in the file is suitable for 12CM*12CM*3.8CM fans, and the duct interface size is ⌀80. If you need to connect a fan with a thickness less than 3.8CM, please trim the model size yourself. I did not add screw holes to the model; instead, it clips onto the fan itself. Inside, I also applied a circle of electrical tape to increase the firmness of the attachment. The duct interface also clips the duct itself, and the duct interface size is quite suitable for a secure fit. I simply modeled this to narrow the air inlet when the fan noise is low, making the air intake more concentrated, to achieve better desktop smoke extraction. I am a pure beginner who just started modeling not long ago. If there are any inappropriate parts, please point them out in the comments, and experts are welcome to optimize the model.
