Air Tunnel Patch

Human: Update 1: For a Better Approach, Check This Out: https://www.thingiverse.com/thing:4352377 The original design is impressive, and I appreciate the effort the creator put into it. However, in my opinion, the air tunnel/room is too large and not properly isolated from the rest of the case. As a result, the SDS011 sensor fan cannot create a vacuum and draw fresh air from outside; instead, it takes air from the case, which acts as a buffer zone. By applying this patch, I've already noticed an improvement in real-time PM readings (in the original design, there were some delays when comparing the readings to a Netigo sensor - an improved version of Luftdaten.info). In addition to this, I hope to improve temperature readings, but I'm not expecting miracles in this respect. A better solution would be a BME280 sensor placed in an attached enclosure to the OBO case. The designers of Netigo sensors use a reduction M16-M20 and a blanking plug with a simple hole in the middle with great success.
