GoPro handle with Boya mic holder

I designed this GoPro handle as I wanted to use an external microphone to record the sound.
The spare microphone cable is stored inside the handle.
The microphone I used is the Boya BY-LM20.
I printed the parts with a layer height of 0.2mm and an infill of 30%.
The upper cap is the only part requiring some support; please print with the threads closest to the the bad of the printer.
I used M3 * 10mm stainless steel countersunk screws to hold the mic bracket and clamp together.
