Print two of these models to join a flexible duct through a screen! Designed specifically for 4-inch ducting, similar to this product:http://smile.amazon.com/FO450-5-ply-Supurr-Flex-Aluminum-Ducting/dp/B00009W3H2/ref=sr_1_2?ie=UTF8&qid=1412923160&sr=8-2&keywords=flex+ducting Use magnets, such as these:http://smile.amazon.com/gp/product/B001ANVAHI/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 , and hose clamps like these:http://smile.amazon.com/Spectre-9704-Hose-Clamps-Pair/dp/B004AJ352W/ref=sr_1_2?ie=UTF8&qid=1412924144&sr=8-2&keywords=4%22+hose+clamp Instructions I printed these models at a depth of 0.2 and an infill of 20%. I had to shave off a small portion to make room for the magnets, which I then secured with gorilla glue for long-lasting stability. When assembling the components, be certain that all the magnets are aligned in the same magnetic direction, while their counterparts on the second print face the opposite direction.
