I was inspired by some aftermarket steel mike holder, but wanted to have a magnetic mount.
The idea how to mount it was inspired by this AliExpress item. It is held in place by the grab-handle screw.
I made it out of the Bambu PA6-CF - it's very light and feels rigid. Compared to the pictures I have made it slightly more vertical, as it will make it fit the mic attachment better.
