About this 3D model

Print in PETG to allow a little flex. This part uses the ‘fork’ from a handheld Swiffer to hold the dusting part. It's a press fit so adjust as necessary if it's too tight or loose. My particular extension arm is a Mr. Longarm model with a tapered thread so this screws on very snugly. There are a total of five positions you can set using a ½" bolt and wingnut. The Fusion 360 .f3d file included if you need to adjust to another bolt size or something.
