Universal 3D-Printable School Ruler Set

Get ready for the school season with this comprehensive, 3D printable geometric set! This collection includes four essential tools designed for students, makers, and anyone who needs reliable measuring instruments.

4 Models in One Set:

• 20cm Straight Ruler: A classic, everyday measuring tool with a fun wavy edge on one side.
• 45° Isosceles Triangle Ruler: Perfect for drawing precise 45-degree and 90-degree angles.
• 30°/60° Triangle Ruler: Ideal for drafting and geometry work.
• 180° Protractor with Straight Edge: Features a built-in straight ruler at the base and a versatile stencil set (circles, squares, and triangles) integrated into the design.

Design & Printing Features:

• Fits on A1 Mini: All four models are sized to fit perfectly on smaller print beds like the Bambu Lab A1 Mini.
• Built-in Stencils: The protractor includes convenient cutouts for drawing perfect circles, squares, and triangles.
• Flexible & Durable: At a total thickness of just 1mm, these rulers strike the perfect balance. They are flexible enough to resist snapping in a busy backpack but rigid enough to provide a solid straight edge for drawing.
• Two-Color Printing: The models are designed for easy dual-color printing to make the numbers and markings pop. The file is optimized for a total thickness of 1mm, using 5 layers at a 0.2mm layer height. The top 2 layers should be printed in a contrasting color to the bottom 3 layers.

Printing Recommendations:

• Layer Height: 0.2mm
• Total Layers: 5 (for a 1mm total thickness)
• Color Changes:
  • Layers 1-3: Base color
  • Layers 4-5: Contrasting color for markings
