I notice recently, there are so many people are selling 3d models as NFT on OpenSea or other NFT markets.
while most of these 3d models are available for free, on 3dripper.com library or rigmodels.com,
is it legal to get these models for free and sell as NFT ?

You have fallen into the trap of thinking that an NFT is the thing itself.

An NFT is associated with something. It is not that thing. Owning an NFT doesn't mean that you own the thing it is associated with. You just own the NFT.

Here's an example:

This is the SHA-256 hash of your post:

Code:

49D06F5C298BC68E14A652D88056041B8EFF795B5D156E63D8D782C62B0C49C3

I could use that, along with a URL, to make an NFT of your post, and I could sell the NFT. Now, would I be selling your post, or just the hash of it, or just some abstract representation of your post?

Now, to answer your question:

Laws vary by jurisdictions, but I don't know of anywhere that is illegal to sell an NFT of anything.
