The aim of this project is to explore the following topics:
- Use of SMD components
- Double-sided PCB making
- PCB art (Odd shaped circuit boards)
- Packing boards together for manufacturing
- Using KiCAD
- Not to mention fun

For people who are going to distribute the finished board (which I assume isn't going to be many):
There must be absolutely zero monetary transaction while you distribute the boards. Do not remove "NOT FOR SALE" text. Keep in mind that this is using a copyrighted material as a part of fan project.
All materials are generated using KiCad and Adobe Illustrator CS6 using JLCPCB's design rules for ease of manufacture as it seems to be an industry standard rule-set.
About Components & Assembly
For the MOSFETs, make sure the pin 1 is Gate and pin 2 is Drain. Make sure the gate threshold voltage is lower than 3.3V and make sure it can withstand at least 200mA. (single-cell lithium battery protection boards use this part)
The crystal oscillator on the daughterboard needs to be affixed to the pad right behind it to prevent excessive vibration and temperature fluctuations.
The battery needs to support at least 250mA of sustained load and must have voltage rating of at least 4.2V.
There should be some marks to indicate what to do - such as signs which look like these:
There are two sets of symbol and an extra to show if you did it wrong:
