A lot of what gets printed on demand costs very little to make. A bracket, a housing, a replacement part for one specific machine. The part is cheap. The design behind it is not. A print is not a single event. There is permission to print, proof that it happened, and payment that follows. Whatever shape that takes on-chain, none of it is free. On an expensive part the bookkeeping disappears into the margin. On a cheap one it is the whole economics of the job. So someone at an OEM goes down the parts list and works out which designs are worth licensing digitally. The answer is the expensive ones. Everything else keeps shipping in a box, the way it always has. That is the test we took into this work with Würth. Not whether a blockchain can secure a design, but whether it holds up on the cheapest part in the catalog. Get that right and the question changes. It stops being which parts are worth licensing, and becomes which parts are worth shipping.
