It defintely can be.
Would not be uber-complicated to build in the ability to publish FCStd files on Nostr, like nostr:npub10r8xl2njyepcw2zwv3a6dyufj4e4ajx86hz6v4ehu4gnpupxxp7stjt2p8 does for APK's.
Same for STL's for your 3D-print app idea.
I bet nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z would even find a way to render them in Amethyst lol 😜
