FeinStoiber case (luftdaten.info)

This is (another) case for the DYO dust sensor of https://luftdaten.info/.

It fits the following components
* NodeMCU v3
* SDS011
* BME280
* DC/DC Converter (DC-DC Step Down Buck Converter Modul LM2596)

This case has the following features:
* NodeMCU antenna has some distance to other metal parts which should have a positive affect for reception
* usage of the DC/DC converter allows higher voltages ( I run mine from 12V) --> voltage drop of long / thin cables has less impact
* no pipe needed
* Stevenson screen for the temperature / humidity / pressure sensor

Additionally needed:
* Hot glue
* small piece of mosquito net
* superglue
* 2x DIN912 M3 30mm screw
* 2x DIN912 M3 50mm screw


Building instructions:
* Print out all parts - only the covers will need supports on buildplate
* I recommend using PTEG because it is more UV stable
* Glue in the SDS011 sensor using hot glue. Use a pen or somthing similar to keep the air in hole open (see picture)
* use h
