A complete parametric 2-plate injection mold (150 × 150 base) in one FreeCAD macro. Change only the 80 × 80 inserts tomold a new part. STL for 3D printing, STEP for CNC, verified by 31 automatic checks, motion simulation and FEA.

• STL (print mode, oriented, all fit a 220 × 220 bed): 12 mold parts, a second insert pair, test-fit standard parts
• STEP: full assembly, print-mode parts, steel-mode parts for CNC, standard parts
• PDF design guide: architecture, how the insert swap works, parameter reference, print guide, standard-partspurchase list, safety; test reports and FEA results
• The complete verification suite (Python for FreeCAD) to re-check your own changes
• Renders, cutaway, exploded view and a mold-cycle animationGood to know: recommended use is a metal mold base with 3D-printed inserts (high-temp resin) for short runs.A fully printed mold is for hand / benchtop injectors at very low pressure (≈1 MPa, estimated). The design has beenverified by checks, simulation and FEA but not yet machined or molded with; images are renders. Macro commentsare in Vietnamese; all documents are in English.
