An ever expanding library of parts modelled in OpenSCAD useful for 3D printers and enclosures for electronics, etc.
It contains lots of vitamins (the RepRap term for non-printed parts), some general purpose printed parts and
some utilities. There are also Python scripts to generate Bills of Materials (BOMs),
STL files for all the printed parts, DXF files for CNC routed parts in a project and a manual containing assembly
instructions and exploded views by scraping markdown embedded in OpenSCAD comments, [see scripts](scripts/readme.md). A simple example project can be found [here](examples/MainsBreakOutBox/readme.md).
For more examples of what it can make see the [gallery](gallery/readme.md).
