<p>This is a air quality lamp for CO2 metering. I used the design from <a href="https://www.printables.com/de/social/102305-lilifee/about">Lilifee</a> (look at the remix).&nbsp;</p><p>The original was for the BME680 Sensor. I needed the case for the MH-Z19. So I changed the inner of the case and the "Top"-part. The “Stand”-part is untouched.</p><p>&nbsp;</p><p>The parts I used inside the case:</p><ul><li>WEMOS ESP LOLIN32</li><li>WS2812 LED ring with 24 LEDs</li><li>MH-Z19b</li><li>4 small screws to keep the ESP and the BME in place ~M1.7x5</li><li>3 screws for the top cover ~M3x8<br>&nbsp;</li></ul><p>I added the "3mf"-file because of the infill trick (look at the blog post <a href="https://blog.prusa3d.com/model-with-prusaslicer-modifier-meshes-tutorial_30438/">her</a>). I used the honeycomb infill with 30%.</p>
