Precision Vernier Caliper V3

Precision Vernier Caliper This 3D-printed vernier caliper combines functionality, accuracy, and easy manufacturing. Perfect for quick use in everyday maker tasks or as a backup measuring tool, it impresses with its robust design and high precision—without the need for any metal parts. Recommended Material: PETG or ABS for Maximum Accuracy Since this caliper relies on very tight tolerances, it is strongly recommended to use: PETG – More flexible than PLA, smooth gliding, warp-resistant. ABS – Higher temperature resistance and excellent dimensional stability for fine applications. PLA – Only partially suitable; can deform or wear quickly under friction. Design Features 🧩 No Glue Required – But Optional: The caliper is designed for tool-free assembly. However, a small amount of adhesive can be used at certain joints for extra durability. ⚙️ Smooth Motion: The sliding unit runs along precisely guided rails. For best performance: Lightly lubricate moving parts with silicone grease or thread lubricant. This reduces friction and greatly improves longevity. 🔍 Fine Graduations: The embossed or engraved vernier scale allows accurate readings—ideal for measuring smaller parts or 3D-printed components. Recommended Print Settings Layer Height: 0.1–0.15 mm for excellent detail and dimensional accuracy. Infill: 80–100 % for maximum rigidity and reliable measurements. Material: PETG or ABS (as noted above). Print Orientation: Print body and slider flat for best accuracy. Supports: Only if necessary for scale details – depends on model design. Why This Project Rocks 📐 High Precision thanks to tight tolerances and smart design. 🧠 Educational – great for demonstrating mechanical principles and measuring systems. 🔧 Ready to Use after simple assembly and light lubrication. 🧰 Compact & Practical – perfect for quick measurements in the workshop or on the go. Conclusion A 3D-printed vernier caliper is not just a useful tool but a brilliant example of functional design in FDM printing. The
