Each project folder follows the same shape:
project-name/
├── README.md model table with sizes, fit notes and download links
├── images/ thumbnails (orthographic isometric, transparent background)
├── print/ .stl and .3mf — ready to slice
└── cad/ .step and .f3d — editable source
Filenames are lowercase kebab-case, and every format for a given model shares one basename, so cad/thing.step and print/thing.stl are always the same part.
GitHub renders .stl files with an interactive viewer — click any STL in this repo and you can drag to spin it, right-drag to pan, and scroll to zoom. No download needed to see what something is.
| Format | What it is | Use it for |
|---|---|---|
| STL | Binary triangle mesh, millimetres | Slicing, quick preview in GitHub |
| 3MF | Modern mesh container, units declared in-file | Slicing — preferred where supported |
| STEP | Neutral solid, no history | Editing in any CAD package |
| F3D | Fusion archive with full feature history | Editing parametrically in Fusion |
All meshes are watertight. STLs are in millimetres. 3MFs are written in inches and say so in the file, so slicers bring them in at the right size.
