This print is an adjustable MIC arm that will fit on most microphones (5/8"-27 thread). It has a VESA mount, so it will attach to the back of your monitor with (4) M4 screws 10mm long. That is the only hardware that is needed. The arm has three joints that can be adjusted in 12 degree increments. The rotation of the bolt that screws into the MIC can be adjusted by using the nut. It is printed in PLA, but other stiff materials should work too.
