About this 3D model

This is one part of a microphone clip for the Thomann t.bone SC300 microphone. It broke 2 years ago and I always wanted to buy a spare part, but never found the time. Now I don't need to buy it anymore, since I have openSCAD and some 3D-printers :) It might also work for other microphones, but I only tested it with the t.bone SC300. Some code was taken from here: http://www.iheartrobotics.com/2011/02/openscad-tip-round-2-of-3.html
