2020 Enclosure/mount for smoke/gas detector FC-22/MQ135

There's an updated version available that includes all schematics and firmware, check it out [here](https://www.thingiverse.com/thing:2548411). This enclosure is designed specifically for use with the FC22 gas/smoke detector I plan to integrate into my printer. The sensor I'm using is this type [https://www.olimex.com/Products/Components/Sensors/SNS-MQ135/resources/SNS-MQ135.pdf] which is designed to detect smoke, CO2, benzene and other gases. Always verify the marking on the sensor itself, as it may be a different model than what I'm using. The type of print is always FC-22. I've conducted some tests with this setup and everything works smoothly. The goal is to mount this enclosure on a 2020-beam in the top part of my printer. Since my printer is fully enclosed, even small amounts of smoke will be trapped inside the top compartment, allowing the detector to function effectively. My aim is to switch off all power electronics (heaters) when detecting smoke and potentially connect an alarm to it. For users who drive their high-power beds directly from the controller, I highly recommend installing one in the electronics enclosure! The housing and mount have a snug fit, and the PCB is fully supported on both sides. When using translucent filament, the LEDs (power and alarm) are visible from the outside. This particular model was printed with PETG at 0.6mm nozzle and 0.2mm layers.
