It is the best if there is a blend file

If you are looking for free commercial use models then those will be harder to find or if you do find them then they will be of horrible quality and not very organized for editing. https://www.turbosquid.com/

thanks for comment.i find few model of royality free in turbosquid.
Does royalty-free mean commercial available?

Unfortunately there isn’t just one answer.
If you read “Public Domain”: this means that you can make the use you want, no restrictions.
As for every other “formula”, better you take the time to read the full license tied to every single website and to every single model. In case of doubt, getting in touch with the website admins and with the model author is the best thing you can do (in some cases, having tried to contact the author has been considered a proof of “bona fide”).

There are thousands of models in .3ds format on archive3d.net. Some of them actually look quite good. Just bear in mind that .3ds format is all triangles. Also there are one or two shortcomings in the Blender .3ds importer, though the patch I posted here might help.
