carbon microphone element

I really loved the way this element was made that it was hollow so I could put an actual microphone inside if I wanted it to be functional.
So I made a few changes.
1) I cut it in three pieces so it was easier to print.
2) I added printed rings to it instead of screwing metal eyes to attach springs. It was easier for me. But you will have to use supports.
3) instead of a bolt and nut through the element I used tinkercad to put a threaded hole. Now you can use a bolt in it. I forgot the size but it's one inch long so it tightens the two outer halves together.

Inside I used some vintage speaker grill cloth which adds to the look of the mic.
I used tinkercad to design an octagonal ring instead of round.
I also used Tinkercad to make the Columbia double sided station flag.
