What are people using to create 3d functional designs?

I see a lot of cheap files on Etsy where it's a somewhat complex 6-sided lantern, or a 3d gingerbread house that's assembled for separate laser-cut pieces, etc. People are selling these things for like $5, so I'm wondering if they're actually modeled in a 3d program or they're using AI to just generate something 3d from a static image? I have some experience with 3d design and related software but these types of files are so ubiquitous and cheap I can't imagine they're actually hand modeled. Any thoughts?

Locked devices between T-mobile MVNOs like Tello?

I've seen some posts online indicating that locked devices on a T-mobile MVNO (Metro, Mint) could be used on Tello without being unlocked since they are both T-mobile MVNOs. Is this still true? I see that most carriers have locked down their devices even more in 2026.
