Where to find 3D printing designs

Millions of 3D models are available for download online, most of them free. It is always worthwhile to search or browse for an existing 3D model before designing something brand new. Adapting an existing model is another option.

The websites listed below are recommended for educational purposes and touch readers. Another quick way to find 3D models is to conduct a Google image search with a description of the desired model and .stl, for example “human brain .stl”.

Generalist 3D model repositories

  • Pinshape – A generalist collection of 3D models with a mix of free and paid designs.
  • Printables – A quickly-growing repository of free models, with categories for educational materials. 
  • STLFinder – A dedicated search engine for millions of 3D printable models, with links to the original site where the model is hosted. It is possible to create an account to bookmark your favourite designs.
  • Thingiverse – By far the biggest selection of 3D models available, with over 2.1 million designs. It has a huge selection across many areas and all models are free.
