Precision Metric Carpenter Square

A compact, durable, and highly accurate precision metric carpenter square designed for woodworking, DIY projects, 3D printing setup, and workshop use.

This square combines a classic triangular carpenter’s layout tool with clearly marked metric measurements and angle guides — all in a lightweight, easy-to-print design.

📏 Features

• ✅ Metric mm scale on the vertical edge
• ✅ Angle markings from 10° to 80°
• ✅ Large internal cutout to reduce material while maintaining rigidity
• ✅ Wide, stable base for hands-free standing

• Tool alignment
• Educational use

🖨️ Printing Recommendations

• Material: PLA, PETG, or ABS
• Layer height: 0.2 mm recommended
• Infill: 20–40% (grid or gyroid works well)
• Perimeters: 3–4 walls for stiffness
• Supports: Not required

📐 Accuracy Note

This tool is designed for precision layout work when printed on a calibrated printer. Dimensional accuracy depends on your machine tuning and material shrinkage.

If you require certified measurement precision, verify with a known reference tool after printing.

NBNBNB No scaling applied in slicer, this should be common sense, but you never know :)
