Powerbank 6x18650 Version 2

After using https://www.thingiverse.com/thing:6316605 for one year, i noticed the long walls bulged out under heat and the pressure from the inside.
This updated version uses an extra pair of screws in the middle and has an extra wall between the PCB and the battery compartment.
