3D printers are worse than I thought. Time to do something about it!

Video Description

Don't breathe this! Thanks to Sunlu for sponsoring a part of this video! Check out their resin and filament options at https://go.toms3d.org/sunlu The Ikea filters I used are FÖRNUFTIG (EPA12 + carbon) and the more affordable UPPÅTVIND (EPA only) If you get a HEPA filter e.g. from Amazon, I'd recommend buying a reputable brand to make sure you actually get what you're paying for. Philips is trustworthy and seems to have reasonably priced replacement filters (important as you'll be swapping them multiple times a year): https://go.toms3d.org/HEPAmazon Read the article to this video here: https://toms3d.org/2024/10/07/3d-printers-are-worse-than-i-thought-time-to-do-something-about-it/ Software and stls for the sensorbox https://www.printables.com/model/993949-3d-printer-emissions-sensor-array Parts and sensors used: ESP32 WROVER https://go.toms3d.org/WROVER ESP32 breakout https://go.toms3d.org/ESPbreakout 2.4" LCD https://go.toms3d.org/24lcd PMS5003S particle + formaldehyde sensor https://go.toms3d.org/PMS5003S (make sure you actually get the "S" variant if you want the formaldehyde sensor - they're a bit hard to find) SDS011 particle sensor https://go.toms3d.org/SDS011 Bosch BME680 VOC, temperature and humidity sensor https://go.toms3d.org/bme680 SCD40 CO2 Sensor (optional) https://go.toms3d.org/SCD40 ScioSense ENS160 VOC sensor https://go.toms3d.org/ENS160 MQ-7 CO sensor https://go.toms3d.org/MQ-7 ...modified with these instructions https://devices.esphome.io/devices/MQ-7 I also used an SHT40 temperature and humidity sensor in the front, but it is noticeably inaccurate. I'm currently trying a AHT21 as a replacement.
