Modmic Headbrace
thingiverse
This lets you attach the ModMic Antlion to your head without any headphones or anything. You will need some 1.75mm neodymium magnets. I use 4 or 5 stacked to increase the strength. This may interfere with IEMs a little, for me the wire sits further outwards, where this headbrace sits right against my head over my ears. Printing it may be a pain. I think you'll have to rotate it. I print it with the circle section against the bed. I suggest approximately 65 degree overhand supports. You may have to finagle, it's not very print friendly.This may not fit your head, I designed if for mine.
