We have a PA System with a corded microphone. We don’t have a way to mount it to the Speaker Stand. I looked online for clamps and mic holders but did not find a versatile version. There was a clamp that I liked but I built this from scratch based on the clamp design that I reference. I used modifiers to strengthen the threads and some portions of the structure. Print the plate as indicated and assemble as shown. The holder can be rotated to the up position if mounted on a vertical or horizontal structure.
