Dropper post lower?

Hi all, just got my self one of those cheapo dropper posts off the bay and wondering how i could get it to sit a little lower as when its fully extended its just a little bit to high, the little black box rests on my seat post collar and apparently the black box needs to have a little bit of float in it so heres a pic

Peronally, I'd just file down the back of the Hope, so it fits under the box.
