The video below provides a model introduction and assembly instructions:

Beyond the printed parts, you only need to purchase a power cord and a fan:

1. 4-pin to DC chassis fan power cord: A shorter cord is recommended (If using a high-performance fan, select a 4-pin or 6-pin connector based on the fan interface)
   
    
2. Adjustable power adapter: 220V to 12V (If using a high-performance fan, select a suitable power cord based on the fan's power rating)
   
    
3. Fan: Any 14cm fan is compatible; fan selection is entirely up to you, ranging from inexpensive chassis fans costing tens of yuan to high-end enthusiast options exceeding one hundred yuan, some even opt for high-performance fans, all work well! Feel free to share your choice!
   

Print Profile Instructions:

1. Compatible with 14025 fans measuring 14cm x 2.5cm [One-Click Print]:
   (Suitable for most fans)
   If, like me, you've opted for a standard 14025 fan, print this profile!
    
2. Compatible with 14038 fans measuring 14cm x 3.8cm [One-Click Print]:
   (Suitable for most high-performance fans), this print configuration is also compatible with 2.5cm height fans
   If you've purchased a 3.8cm fan, or wish to experiment with both 2.5cm and 3.8cm fans, choose this profile!
   
   Below is a comparison of the purifier's appearance with the two profiles (different heights):

Added Fun (Easter Egg):

If you've watched the video above, you'll understand the purpose of the two additional print profiles below.
These profiles aren't strictly necessary, but printing them will add a significant element of fun!

• Custom Air Outlet Pattern Print Profile:
  This profile is a model of the fan's air outlet; after opening, you can adjust the sparse infill pattern and infill density options to design your own outlet patterns! (Specific operations are demonstrated in the video)
  A word of caution: Not all sparse infill patterns are suitable for air outlets, let's see which fool chooses concentric circles…
   
• Aesthetically Pleasing Small Windmill Print Profile:
  For both the 14025 One-Click Print Configuration and the 14038 One-Click Print Configuration, I've reserved space in the center of the standard air outlet for decorative elements. My design is a small windmill that rotates with the airflow from the outlet, providing a touch of beauty while the air purifier quietly cleans the air!
  Note: The rotating part requires a single MR128 miniature bearing, easily available at the TuZhu store.
  
  I may continue developing several interchangeable small decorative elements to rotate on the device, feel free to print and place them as you like.
  However, I hope this inspires your own creativity and ingenuity to design various small decorations for your air purifier!
  And, you absolutely must share them with everyone!!!

Happy printing everyone! Have fun!
