Free cad blocks https://dwgfree.com/cad-blocks/
I just looked at the https://www.cadforum.cz/catalog_en/ site, and it only has 16 free drawings, though many of them have multiple items. There are a similar number of textures.
On the https://dwgfree.com/cad-blocks/ site, has 250 free drawings. But, many of them are libraries having many drawings in the set.
Here is another one that I have used for many years. It has a very large library, with many formats, and many types of files, such as textures and LISP. It also has a good filtering system to help you to drill down to what you want. The main weakness is that it only shows a very tiny thumbnail of the drawing file. So, you have to download it to really see it. And for us U.S. based users, the library tends to lean towards metric/European models.
