Microphone holder for Shure 520DX by bjoerngiesler. Design available here
You will also need a steel threaded insert
to attach this holder to your stand, and probably an adaptor
to get it to the regular mic clip thread size.
Selling for cost. This works well with the Shure 520DX Harmonica Mic. I added a Ball-Joint Mic Adapter
to mine to get the tilt just right.
