This is a mic handle designed to fit a DJI Mic wireless transmitter module. The handle holds the transmitter unit securely by the clip and is designed to fit a foam windshield with a 40mm opening. From experimenting, the cheaper windshields found online are often inferior quality foam and do not hold their shape as well.
The model prints “upside down” with supports. These can be easily removed after printing. The height of the handle and rounded base mean it is not stable enough to print the “right” way up.
The author marked this model as their own original creation.
