edit: misquote, but still the point stands:
Tobias had the injection molds made for both trays and hucard plastic, meaning he's the sole manufacturer of them for the time being. This also means he profited a shit ton with his previous antics AND will profit a shit ton more in the future if people keep advertising his stuff like it has been done before.
He benefits from economies of scale and initial investment now and any repro is possible, though I don't think he'll ever try a Sapphire again since he's pretty well off just doing "normal" reproductions.
