Grove sensors screws/studs

I 3d printed a plastic board where to lay my sensors.
I don’t know however what I need to keep them in place. On the sensors there are little holes where I guess I am supposed to put little screws/studs.
Does anybody know the measures and where I can find what I need?

Hey @LuCavallin are you looking for the dimensions of the PCB board (IE the inner dimension lengths of the holes on the Grove sensor?)?

Yep, I need exactly that!
