what size screws fit in the threaded holes on the bottom of the smart controller?

[Citizen Flier]

Just received the Smart Controller neck strap rig. Seems decently made. Soft gaskets near the threads add tension to possibly prevent unthreading. Better quality than I expected for $19. (from B&H)
Rig seems like a workable option to prevent the tragedy of dropping the baby.

Don’t waste your money on the sunnylife lanyard that has the two eyebolts.
The fit on the eyebolts is really sloppy.

@Starz are you still selling the screw mounts? I have the new RC Pro and am looking for a lanyard solution

Yes.
