Elegoo Mars Endstop Seal

thingiverse

When trying out my new Elegoo Mars, I immediately detected a foul resin odor coming from the printer while it printed. On closer inspection of the build chamber, I noticed that there's a massive opening where the endstop is mounted. Here resin-contaminated air seeps into the metal body of the printer and escapes into the room through this gap. This seal closes the gap by tightly sealing the sensor against the metal walls. It's printed from SainSmart TPU, but any flexible filament should do the job. Enjoy and don't give up on installation as it requires a really tight fit! UPDATE! I printed my first test print after installing the seal today and can barely smell any resin in my room. It appears that the gap around the endstop was the only one between the upper and lower chamber.
