100mm Elbow Fitting for 4 in. Flexible Duct
byMake AnythingI printed this elbow fitting to improve the connection for my dryer's ventilation. I printed it in Fillamentum ASA(Also on MatterHackers) and it has held up great for about a year so far!
Print solid with many shells. It can technically print without supports but I used a tiny bit at at the center of the elbow for a cleaner print.
