Shorty DiD refill screw

[Starlyte2]

My new DiD, Short version, is now short of the filling screw, which made a jump to G knows where, the FIRST time I wanted to fill it. OK I am clumsy, have arthritis, but I've searched everywhere, no luck
Anyone know where to buy DiD spares, such as filler screws? Pleeeeeze
I haven't even tried it out yet

Have you tried using it without the screw? Some recommend it for a better vape. I know I do for sure.
