4 Inch Ducting Simple Mounting Bracket

I needed a way to securely mount some 4 inch ducting to the bottom of my desk so I designed this simple bracket. It had to be easy to use and I didn't want to deal with multiple parts or extra hardware that would be difficult to deal with under a desk. I made it fit a small command strip on the flat section, but you can use whatever you have. All you need to do is slide the bracket(s) over the duct before installation and stick them down where needed. It's open on the side so that it's easier to feed the duct through, it should flex just enough so that it doesn't get caught. If you have a long duct then one bracket will likely not be enough to hold it up alone, unless you use stronger tape or screws, but putting one every couple of feet worked for me. The bracket has an inner diameter of 110mm/4.33 inches as I found that making it a bit bigger made it easier to slide onto the duct but was still plenty strong. I have printed it in PLA, PLA +, and PETG with good results f
