I broke my mic's shock mount outer trying to brute force it without loosening it, oopsie.
Used with the kit that came with my bm800 mic, usually cheap mic arm kits from amazon have the same shock mount.

Printed in eSun PLA+ with a 10-20% infill, anything will probably work
Keep in orientation of stl and print with normal supports.

If needed, i can also design the inner mic holder bit
