Just around 1 hour to print!
A simple holder/mount to attach a suspension boom mic with a 3/8" female adapter to a monitor arm. I have a dual monitor arm with a long pole sticking out the middle, and this helps mount it. The screw tightens the mount around the pole.
The diameter of your pole should be around 1.4" or 35mm. It can be slightly larger or smaller than that. Recommended to print in strong material like PETG with high infill percentage, at least around the thread.
