4in Duct Flange

Custom made 4in duct flange that is pretty quick to print. Designed to be strong, and practical this is your choice for your ducting. The portion that attaches to your ducting is slightly oversized for a nice tight fit, and the base has been designed to work with four regular 82 degree tapper dry wall screws.I made mine from Atomic black CF PETG with fuzzy skin to really make the model look clean and not so much like a 3d printed part. .2 layer height2 perimeters
