If this becomes law, it will give rise to a fun new form or protest art in this vain. What is the cutest thing you can design that nobody would consider to be related to guns, but which gets flagged? An obvious example... a llama sitting on the ground, legs hidden, and head held high in the air, chewing its cud. Llamas can be really cute! Sell them on Etsy/eBay/etc., printed by an out-of-state 3D printing service. I just used the EFF form to promise my state senator in Sacramento that I'd send her (and reporters that cover her) one of them if the bill passes.

Conversely, add cute animal models to gun parts.

Maybe it would be possible to just embed a prompt injection into metadata or the STL mesh itself.
