case for dust sensor SDS011 plus BME280 mount

thingiverse

I modified the original case by kleinerELM. Changes * Added a pocket for a 4 pin style BME280 - may need a drop of glue for fastening the PCB * Reduced the tube orifice to 9mm for a snug fit and removed it on the right side * Reduced the bottom USB cable inlet * Enlarged the weather protection shield on the left +20mm * Moved the tube orifice 5mm to the rear side What failed * Added covers above the wall mount holes to make the rear side weatherproof - failed as the SDS011 needs this space - ripped them out and closed the wall mounts with Bondic UV adhesive. Thus they were removed from the model. * Added a perforated cylinder between the left weather protection shield and the air inlet with 1mm holes and 1mm land between them. Without internal supports this was also a failure. Conclusion Most changes were made to make it more difficult for insects to settle down in the case (but I'm sure they'll do so nonetheless) and to protect the BME280. The tube orifice was moved 5mm to the back as it was not in line with the inlet of my SDS011. The 5mm were guessed and I've not yet printed the case after changing it as the current one still gets the job done. Update 2019-03-16 As requested, I added another version of the case with a different cut out for the BME280
