Description of Combination Wrench Using 3D PrintDesign ConceptCombination wrench is a manual tool consisting of two ends: Open-end:The open end used to tighten or loosen bolts and nuts. Box-end: Rounded closed end (usually has teeth on the inside) for better grip on nuts or bolts.3D Print Setup Filament Material:PLA: For educational or decorative purposes because it is easy to print. PETG or Nylon: For more pressure-resistant and flexible tools, suitable for light functional use.• Print Resolution:0.1 – 0.2 mm: To maintain detail on the open-end and box-end.• Infill:50–100% Maximum strength required, especially at the neck (shaft).• Supports:Not necessary if the design is oriented horizontally with flat sides. If printed vertically, use supports for stability.• Print Speed:40–60 mm/s Medium speed to prevent printing errors.• Model Dimensions:Adjusted to the targeted nut/bolt size, for example the total length of the wrench is around 15–20 cm for general use.How to Use a 3D Printed Combination Wrench• Tightening and Removing Nuts or Bolts: Use open-end for light work on easy-to-reach bolts. Use a box-end for a stronger grip, especially on bolts that are tighter or located in tight areas.• Limitations: Avoid using nuts or bolts that require high torque, because printed materials (especially PLA) tend to be brittle. Use for light tasks such as DIY projects, toys, or educational models.• As Education: This model can be used to study the working principle of a wrench and how its various ends are used in different situations.
