7" Range Hood Damper

pinshape

I just installed a brand new range hood and it didn't come with a damper so I purchased one made from sheet metal. Unfortunately, this new addition was an absolute disaster! Any quiet advantage I had gained by buying a new range hood was completely destroyed by the constant clanging of the metal damper. So then I thought to myself, "What if I could create a custom damper and print it?" Ah ha, a brand new 3D printing project! I was extremely satisfied with the results. It is highly unlikely that I will ever print more than one of these in my lifetime, but I am uploading this design here on the off chance that it might help someone else who's struggling with a similar problem. Print Settings Printer: Prusa i3 MK2 Rafts: No Supports: No Resolution: 0.350mm or finer Infill: 20% Cubic Notes: Printed on a Prusa i3 MK2. I used ABS for this project. (Scale up by 101% for shrinkage.) PLA or PETG can be printed at size. Print one base, one ring, and two flaps. If your range hood accommodates 3-1/4-in x 10-in ductwork, you may have to print the wings to cover the wide hole. Post-Printing Assembly This design uses thin stiff wire for the flap hinges. I had some spare 15ga bicycle spokes that I used, but a suitable diameter of music wire would work (available in hobby shops.) Cut the wires to length and insert them into the holes in the base and flaps. Slide the ring down over the wires to keep them in place. (You may want to glue the ring if you prefer it to be permanent.) Customization My particular range hood is a GE model JVX5360SJSS. This design can be customized for other hoods with 7" diameter ducting by modifying the design to place the holes in different locations (or you could print it as is and drill new holes into the plastic.)
