Tinkercad-style shape modeling with fillets, threads, sketches and CAD exchange for 3D printing.
A local-first browser CAD editor derived from SketchForge-3D. Reproduces Tinkercad-style shape placement, solid/hole grouping, alignment and workplane interactions, adding OpenCASCADE-backed edge operations, shelling, sketches, threads, patterns and STEP/STL/3MF exchange. Designs remain in browser storage or a self-hosted project store; local MCP control is available.
