This Pattern Ruler is a 3D-printable tool designed to help you keep track of your place while working on detailed crochet, knitting, or embroidery patterns. Whether you're following rows, charts, or symbols, the ruler makes it easy to stay organized and avoid mistakes.

The model is designed to be assembled after printing. You can choose between two assembly options:

• 4 magnets (5 × 1.5 mm) — used to click the two parts together for a smooth, secure sliding motion
• 2 elastic bands — a simple and flexible alternative for holding the parts together

Both options allow the ruler to glide along your pattern so you can easily follow the line you’re working on without losing your place.
