Vent Exhaust addon for Mars 3
thingiverse
I keep my Mars 3 in a fairly ventilated room, but the fumes can still get to me, so I too the Elegoo Mars 3 heating module by Venko (https://www.thingiverse.com/thing:5222208), and remixed it to only have the vent portion and not the rest needed for the heating module. I used a 50mm 12v fan (https://www.amazon.com/gp/product/B0837YKXXF/) as well as a PWN speed controller (https://www.amazon.com/gp/product/B09NBD96SV/) all hooked into a 12v power adapter. The vent itself is designed specifically for the hose I am currently using (swimming pool vacuum hose), so keep that in mind if you print it for yourself. It can print all in 1 piece on an Ender 3 V2, or Ender 3 Pro, if you are configured to make the most of your print bed (230x230) print upside down to minimize supports required. Takes about 24 hours to print. Added a 90 degree exhaust vent, which will need supports when printed.
