She Who Must Be Obeyed did not appreciate the odor, even though there was acceptable ventilation. In order to maintain household happiness, I endeavored to find a fume extraction system. In my searching, I only found solutions that require modification to the printer housing, or did not promise much actual fume extraction. It wasn't until I had already started my own design that I found some viable alternatives. But, since I had already ordered a fan, and was almost done with my design, I persisted. In the end, I have a fume extractor that does not change the air flow dynamics of the printer, requires no modification to the printer that is not easily reversible, and has been doing a great job at keeping the odor to a minimum (so far). With some 3" flexible ventilation hose, and a 120mm fan of some kind, you should be able to print this, set your printer on it, and the fan in a window, and continue to lead the happy life you wanted with your happy wife.
I've included the STEP file so you can make easy modifications. I appreciate if you post a remix, if you do any mods.
The photos should be as follows:
- Completed Fume Extraction System.
- Main body of fume extractor, the base that the printer sits on, shown upside-down. It should be printed as provided and fits on a Prusa bed.
- Super Lube (or similar grease) helps get tight printed threads to work more easily. Try it!
- Feet installed (with leveling foot adapters installed)
- Right side up, with feet installed
- get a long enough zip tie, or use multiple zip ties that can go around the hose adapter.
- Thread on the vent hose, and secure with zip tie
- Lots of hose. We'll cut to size during installation.
- Fan adapter printed
- Fan mounted to window insert (made from coroplast I had on hand) with a little window gasket to help.
- Outside of insert showing fan output
- Adapter mounted to fan and window insert.
- Window insert installed
- Estimate needed hose length. Cut, and install onto fan adapter with another zip tie(s).
- base in place... almost ready!
- Stuff in your favorite activated carbon filter material.
- Place Elegoo Mars on base. It should just sit right in (see first photo)
- The hose can bend a lot, but don't pinch or kink it!
- My resin printing corner of the room.
