All of these Materials are easily available on Ebay and for the materials for two units i paid 20$ per unit.

For the assembly you wire the LEDs in series and connect one lead to the switch and the other to on of the

 the outputs of the Charging PCB. You connect the switch to the other output. Pay attention not to wire the LEDs in reverse. You also have to solder the LiPo Wires to the Battery connector on the PCB. The two slits in the print are for the switch and the USB-C port. the LEDs go into the grooves of the printed ends of the shell. PCB, Battery and LEDs are hot glued in place and the enclosure can be closed with tape. To Check wether the LEDs are lit up you can check with a phone camera because the human eye cannot see IR light but Phones display it as a violet color.

You need to open up the PS3 Eye camera and remove the IR filter and replace it with a floppy disk cutout a tutorial is linked here:
