Peopoly Moai Air Handler (smell reduction/removal)

thingiverse

This is an air handler/smell elimination strategy for the Peopoly Moai that assumes you've already added a chamber heater with a 12-volt power supply. See the following for more details: https://www.thingiverse.com/thing:3326032 First and foremost, seal around the edges of the door of the unit with medium window seals as shown in the images; these can be found at home depot or online, just ensure you use the foam kind without any surface texture. After sealing the top, right, and bottom sections of the door, reduce the amount of exposed gap on the left side of the door by adding a few strips of electrical tape. After finishing this step, notice a significant improvement in the amount of smell emitted by the printer, but it won't be completely gone. The filter here uses HEPA filters to protect the resin in the vat (reduces particles per cubic foot inside the chamber) and active carbon to remove volatile organics (that nasty smell). You'll want to use metal mesh in addition to the printed plastic grates to keep the active carbon in place. While the parts fit pretty snugly together, it's a good idea to secure them with 4 x M3x8mm (5 mm works too) screws and 4 x m3 nuts. From top to bottom, you should have parts in the following order: 1) Hepa mount 2) Hepa filter: https://www.amazon.com/gp/product/B01I2QUCOM/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 3) Grate 4) Metal Mesh: Woven Wire 60 Mesh 12"X 24" 30cm X60cm x0.25mm Papermaking 304L Stainless Steel 39% Open Area 5) Carbon holder filled with active carbon: https://www.amazon.com/gp/product/B0002566WY/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 6) Metal Mesh (the grate below this is embedded in the carbon holder) 7) Fan holder (don't fill the empty space here it's for air flow) 8) 2 x Fans (be sure to orient them so they pull air through the assembly, not push): https://www.amazon.com/gp/product/B074ZF7Z66/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 9) Fan Grate (optional) After printing, you'll need to solder the fans together and then power them with 12-volt. I piggybacked on the plug used for the heater I previously installed; be careful not to reverse bias these fans.
