By default this works with a 30mm thick desk and scews with under 5mm shaft but a bigger than 5mm head but this can be changed if you open the original fusion file, it uses an m6 bolt in the side to secure the microphone arm to the mount.
Print it with 25% or more infill and positioned so the holes are printed vertically or 45 degrees, if the shaft is printed horizontally it will snap.
