The 520DX is very popular with harmonica players and some singers use it as a special FX mic due to its specific mid-range tone. But when you're not cupping it in your hand, you can't put it anywhere. There's no mount for a mic stand, and the round shape and heavy cable mean it's prone to fall off a table. This clip holds the mic tight but it's easy to take it out. The mounting block has one hole for a 5/8"-to-3/8" adapter (mount top of mic stand) and one that can be threaded for M8 (mount anywhere else).Quick instruction: Print the file named "520DX.stl", buy a 3/8" thread adapter (e.g. a K&M 217), glue it into the large hole. Done. Long instructions: The reason for the complicated path is that the rotational shell won't render correctly using the standard OpenSCAD render (at least on my machine) and takes ages to render using CGAL, so it's awkward to work with. So the rotational body is created first, and post-production is done in a different SCAD file.
