Snowflake light base (rechargeable)

Update Log
June 7, 2024 First Update:
This update improves the 3D printed base shell. It no longer uses two plates joined together or has a hollow design, resulting in a more aesthetically pleasing appearance. The 3D shell file is attached. The Type-C male connector has also been updated. Feedback indicated that the previous version's Type-C male connector was not sturdy and easily damaged. This update resolves this issue with a new, more robust Type-C male connector. The link to the new Type-C male connector is also updated below. See the following images for the updated base:
 
 
 
 
 
The snowflake lamp designed by mondraker is irresistible, but it's very inconvenient to use without a base. I've seen bases powered by power cords before, but those weren't very convenient either. The snowflake LED normally requires a 5V power supply, but I found that it also works fine with a 3.7V lithium battery. Therefore, I simply used the TP4056 power management chip with the lithium battery, eliminating the need for an additional boost circuit or power supply chip. Only a few resistors and capacitors are needed, making it very cost-effective. Here are some of the component links for

M2 screws: Buy M2x4 size. Copper pillars should be purchased according to the battery size; this is for reference only. Assembly: The upper board is soldered; the lower board does not need soldering. Simply connect the upper and lower boards using copper pillars and screws. The battery can be soldered directly (pay attention to the positive and negative terminals!).
