Base of the microphone stand. This base is used also for PA stand. Just add tubes, bolts, nuts, and piece of rubber.

Brake is part of source code. Divide it from the main body in the code or use "Split to objects" in slicer (Slic3r). Glue a rubber to the brake so it breaks much better. Break hull accepts hexagonal nut. You can change it to squared nut in the code.
