Made this on a whim and so it is functioning but not best it could be. Currently this is only made for the miller 256174 headgear like https://www.thingiverse.com/thing:1620362 is made for. It might be able to be used on others and I have included photos to show the mechanism because I am not sure if this is standard.
This uses the original screw but because of that it isn't the strongest I will add another model with a longer screw that you would have to buy. This does function and is strong enough to hold the Vive by though I don't recommend. I broke mine overtightening so be careful but super glue fixed it just fine.
