Beyerdynamic MM1 Ground Plane Measuring Base

This is a microphone base I did for the Beyerdynamic MM1 measuring microphone to do Ground Plane Measurements. Usually the microphone sits completely on the floor, and due to the larger diameter size near the connector, it sits slightly higher than it could be, if you put tape on it sometimes it moves from the position. With this base you could put the diaphragm much much closer to the ground and in theory you could measure higher up without artefacts. It has two different sizes, for MM1 you need the short one. It needs a m5 nut, m5 washer and a 1 inch 3/8 hex screw. Boost Me
