step.parts is an open source directory of 12,000+ STEP parts for your next CAD project.
Many CAD tools like Autodesk have huge closed libraries of standard mechanical and electrical parts.
The goal is to build an equivalent catalog for the open source CAD community (that’s easy for humans and agents to use).
The directory is seeded from dozens of existing open source catalogs and generators, catalogued and organised by family, standard, size, etc.
The directory also includes an API, llms.txt and skill to make it easy for agents to download relevant STEP files in generative CAD tools. I’ve added the skill to my text-to-cad repository:

I’m hoping many can contribute to the repo and expand the directory to hundreds of thousands of standard parts!
Happy building
