Fume Extractor

thingiverse

This is a simple fume extractor for a resin printer enclosure. You will need an 80mm fan. I made the external duct removable when I am not using the printer and want to close the window. There is a recess in the hose duct connector for a foam rubber sealing strip. This gives an airtight seal when the hose duct is attached so that fumes do not leak back into the room. I used some old pool cleaner hose which is easy to cut to length and screws into the hose connectors. You may need to design and print your own connectors to suit whatever hose you intend to use. I have a convenient window next to my printer, so I simply cut a rectangle of coreflute plastic to fit in the window opening and attached the two window panel connectors to this. The window panel connectors also have internal grooves for sealing strips.Print one or more spacers if required to allow the hose duct to slide onto the external fan mount if your enclosure frame is in the way. The fan mount has holes for running the fan power leads through to the exterior of the enclosure (you will need to make a small hole in the enclosure wall for the wiring. The fan, fan mount, spacers and external fan mount are assembled with four bolts and nuts - length will depend on your enclosure wall thickness and spacers (if used.)The hose duct, hose duct connector and hose connector cover need to be glued together. Two hose connectors are glued into the hose connector cover.You should be able to see how to assemble from the photos.I hope someone else finds this useful.
