Interesting. Seems like the flat die (spoiler: works like a cookie cutter) would work fine on a much smaller scale. For example, you could manually press it down on a piece of cardboard, maybe with a lever action. A cursory search seems to indicate such contraptions exist.

Seems like that ought to get you up to laser cutter speeds (3 mins/part) with a much smaller investment.

PS - not usually one to complain about this, but the contrast of the font on that page is ridiculous.
