No 666 for CUTEK mini fan

Simply sharing a brand new design. Since I couldn't find a power bank online that I was satisfied with for the CUTEK CP mini fan, I decided to design one myself

I will upload the detailed assembly steps when I have time. If you want to make No 666 yourself, here are the materials you'll need:

• One CUTEK CP mini fan
• Two 21700 battery cells (recommended: Changhong Sanjie 21700-5500, around 20 RMB for two, higher capacity and cost-effective)
• One 22.5W charge/discharge integrated digital display main board (single Type-C port, please find the same model according to the pictures I provided, otherwise assembly will be troublesome)
• Two red and black parallel wires (one 15CM, one 20CM or longer)
• Two colored wires (both 15CM, for USB signal, otherwise the three gears cannot be stable)
• One USB female port (please find the same model according to the pictures I provided, otherwise assembly will be troublesome)
• One set of battery spring contacts (please find the same model according to the pictures I provided, otherwise assembly will be troublesome)
• Soldering iron, solder, and wire strippers
• Hot melt glue, and super glue or 502 glue (please note both types of glue are needed)
• AMS (only the front buttons must be printed with AMS; other parts can be achieved by pausing at layers to change filament. If you don't care about the two small blue strips on the front, you can ignore AMS)
• Smooth printing plate (needed for printing the front screen and transparent exploration version)

For convenience, here is the organized shopping cart

Then you also need to buy battery spring contacts on PDD

For other tools, just choose what you like
