Precision Vernier Caliper V3

📏 3D Printing Project: 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
