Kerastase Bottle Cap Dispenser

I like the Kerastase shampoo but the thing that grinds my gears is the fiddling around with the big bottles to get a good amount of gel out of them and putting the cap back on all with wet hands. So I designed this cap replacement with matching threads and a 2mm hole so I can just flip the bottle, give it a little squeeze and get the desired amount of shampoo without needing to undo the cap, then put it back.
