Nobody owns it.
Not even me because this wasn't mine idea. I just put the specs on paper.
It's just a curiosity design.

Ah. Ok, to be clear, you don't 'own' anything except for your own rendition of it. And as I suspected, what he gave you was permission to do a derivative work. Permission to do a derivative work is granted by the
SbFUA, so long as you follow the crediting rules in said agreement.
