Some older Blue Yeti microphones have a larger, non-standard threaded mounting hole, which doesn't fit the standard 5/8" mount on most mic boom arms and mounts. One side of the adapter threads into the non-standard mounting hole of the Yeti and it exposes a standard 5/8" thread.
Printed in PLA without supports at 10% infill and .12mm layer height. Tolerances are tight, so if you find it doesn't fit, scale it down in the x and y axis in your slicer.
