Sometimes we need some inspiration or specific skills to design a decent 3D model. Fortunately, there are several 3d file hosting services providing access to various models which are available to wide community of makers and 3D hobbyists. Please find my top 8 websites which allow to explore and download 3D models (in STL or other 3D file extensions).
For some of them you must sign up in order to download a file, for some you don’t need it. Also, please be aware that most of models are not intended for commercial purposes
