About MilliCAD

MilliCAD is a simplified CAD tool for turning 2D shapes into 3D models and exporting them as STL files ready for 3D printing or further CAD work. It's aimed squarely at simple, single-part geometry — not full assemblies — so you can go from a 2D sketch to a printable file quickly, without learning a full-featured CAD application.

How to use it

1. Sketch or define your 2D shape/profile.
2. Set extrusion depth and other 3D parameters to convert it into a solid.
3. Preview the resulting 3D model and adjust as needed.
4. Export the model as an STL file for printing or further editing.

Who it's for

Makers and hobbyists who need a quick STL for 3D printing a simple part, and anyone who wants to go from a basic 2D shape to a 3D model without a steep CAD learning curve.
