I'm curious if there is a source of free downloadable 3D models of electronic parts.
I'm looking to use them only for some rendering experiments (not really designing actual functioning boards), but that's why download-ability is necessary.
I assume most standard formats will work fine for the purpose.
Since it's only for a little bit of playing around, I would like that they are either free and open source (or public domain or creative commons share-alike or other licenses that allow usage and modification).
After a quick search, I did run into at least one website offering parts, but it says "buy membership", so it's not suitable.
