Spring-shaped flowing lanterns wish you a Happy New Year

This is a "Spring" character-shaped flowing light, modified from a Christmas tree design sold on Taobao. The project includes A/B base plates and a 2mm acrylic shell.
The first version of the red PCB for the "Spring" character flowing light
 
consists of three parts: A, B, and the base plate. Soldering is very simple.
The PCB thickness is 1.6mm.
 
Features:

compatible with through-hole and surface-mount components (the light uses individual straw hat LEDs).
Two power supply methods are designed (Type-C direct power supply with switch, 5V 2A boost module).
The shell is custom-cut from 2mm acrylic on the panel, and it is also compatible with Christmas tree kits from Taobao.
Original components from these kits can be purchased and used on this board.
Components can be purchased according to the BOM (using P3 3mm RGB fast flashing LEDs, or red and yellow LEDs).

 
Demonstration:
 
Soldering steps and instructions.
 

Each board has three 4.7uF through-hole capacitors and surface-mount capacitors, with positive and negative markings printed on them.
Resistors on board A include R1 and R2. R3 is a 4.7kΩ resistor (compatible with 1206 SMD and DIP). R5, R6, and R7 are 100Ω resistors (compatible with 1206 SMD and DIP). The LEDs are marked with the positive terminal
resistors on board B, including R1, R2, and R3, which are 4.7kΩ resistors (compatible with 1206 SMD and DIP), and R4, R5, R6, and R7, which are 100Ω resistors (compatible with 1206 SMD and DIP). LED D19 needs to be bent and soldered flush with the board; otherwise, it cannot be installed on board A.
For the rechargeable version of the base plate, you need to purchase a 5V 2A charging and discharging module and install it according to the hole positions. Use a 6x6 horizontal plug-in switch with a length of 4-6mm. Select a 103050 lithium battery with the highest capacity. For
the direct-plug version of the base plate, you need to solder a TYPE-C female connector and a self-locking double-pole double-throw switch.
Refer to the PCB information and soldering tools to complete the soldering. Use M2*10 screws and M2 nuts for installation and fixation. Wishing everyone a happy Lunar New Year of the Dragon! Thank you!
