Mechanical Parts and Pipe Fittings Collection

A collection of parametric mechanical parts and pipe fittings modeled in FreeCAD. Includes fully constrained sketches, turned and lofted components, pipe sweeps and helix features, assemblies with mechanical joints, and TechDraw documentation. Deliverables for each item: .FCStd source file, STEP for CAD exchange, STL for 3D printing (where applicable), and TechDraw PDF; DXF/SVG exports provided for 2D/CAM needs. Models are designed with DFM considerations (fillets, chamfers, shell, draft) and include basic tolerance and print/CNC notes.
