Soldering fume extractor

I could'n find any fume extractor here that would suit my needs, and didn't really want to buy a commertially produced one, so i created my own!

It was design to house a 120x25MM PC fan and two 120x120x10MM active carbon filters easily accesible on Ebay or Aliexpress for pretty cheap, plus a single or perhaps double* (paralleled) 18650 cell battery equipped with a USB charger module and a standart boost converter, and a small rocker switch. Mine was of around 14x9MM mounting size.

off-the-shelf modules:
TP4056 uUSB li-ion charger
MT3608 2A step-up converter

The whole thing fits perfectly on the ender-3 and can easily be printed as one model. Keep the orientation as is! Of course feel free to ask me in the comments if you have any questions regarding the assembly of the device.

*There might only be enough space for 1 battery, depending on the way you put the elecronics together. I am using one high capacity cell, giving me enough time on 1 charge for any soldering job.
