When recording, capturing good stereo images can be surprisingly difficult. A well-known technique is the ORTF microphone arrangement, in which two cardioid microphones are at an angle of 110 degrees to each other and are separated by 17 cm to obtain a stereo separation effect that is easy to reproduce.As we all know, we used a pair of Shure SM58 and a bunch of Post Office rubber bands to do things in our school days, but [marsairforce] Do better A very neat 3D printed microphone clip.
Designed in OpenSCAD, the first iteration of printing on a resin printer proved too fragile for the task, so the second version was printed on the FDM machine. This includes significant reinforcement, as well as screw mounting of the microphone holder. The result is very useful and cheap for any recording setup, and anyone struggling to get a good stereo image will love it. You can see some of them in the video below the break time.
