icrafty

icrafty is an app for turning repair and upgrade requests into CAD models for 3D printing. AI designs the solution first: it analyzes the problem, works out the part's geometry and dimensions, and generates the code that builds the model. The app redefines "broken" to include things that no longer fit your needs: a missing cap, an awkward grip, or a design you want to upgrade. Capture photos live from your camera or import existing images, then draw and add annotations to show what needs fixing or changing. The AI analyzes the original photos and your markings, asks for missing measurements, and uses Codex's native image-generation tools to sketch possible solutions. Inspect or annotate a generated sketch and send it back to refine the design in the same saved conversation. Original photos and generated concepts remain available throughout the discussion. The first demonstration focuses on a replacement mug cap. The CAD workflow uses FreeCAD to build solid geometry, render views, compute geometric checks, and export STEP files for print preparation. The app combines live Codex chat, camera capture, editable annotations, inline measurement forms, and an interactive STEP/STL viewer.
