Fume Extractor Box with fixed Charging Module (Remix)

After I printed the original model I realized I had to fix the charging PCB somehow inside the box, so a USB-cable can be plugged in without the PCB moving away.

After a quick thought about just using glue I decided to make a new box, in which the PCB is hold in place. This is reached with a seperation in the box, that allows the cables to pass through and an additional top piece that is placed upon the inserted pcb to lock it in place. The fan then holds that top piece in place.
