Description
Precise Protractor & Ruler Combo
An elegant, sturdy, and absolutely functional geometry tool, completely designed from scratch in OpenSCAD. This model combines a precise 180° semicircle (or 360° full circle) protractor with a centimeter ruler (-5 cm to +5 cm) directly on the central connecting bridge.
Intelligent Text Layout (No Floating Numbers): The critical numbers for 0° and 180° have been mathematically shifted so that they lie flush on the solid base ring, instead of hanging in the air over the inner recess.
