I modified the holes to work perfectly with 2 M3 bolts and mount flush. For the base, i used a dowel connector (depending on your printer settings, you may or may not need to slightly sand the dowel down a bit). 

If you use Bambu Slicer or Orca, you should be able to edit the initial text on the custom text plate and make it your own. 

I printed it in Creality Black Hyper PLA and AzureFilm Silk Gold at 0.12 and 0.16 layer height.

Use supports for the dome part of the mic, paint it on the dome, just don''t use auto). I also tried to included the 3MF that i used on my P1S, but doesn't upload.

For assembly i glued the small gold base to the main base. Next, i glued the dowel and connected the arm. I installed the M3 bolts to the ring and as a last step, i just glued the 2 mic half inside the ring itself.
