The Foldable Modular Ruler & Stencil Set is a thoughtfully designed, multifunctional tool ideal for students, designers, and journaling enthusiasts alike. This modular system allows you to carry up to six interchangeable stencils on a compact foldable base — offering maximum versatility without the bulk.

This set includes both metric (cm) and imperial (inch) versions, along with a curated collection of prepared stencils:

• Simple rulers (cm/inches, top, bottom, or both)
• Radius guides (for drawing precise circles)
• Vertical line templates (perfect for tables and repeated lines)
• Dotted and arrow patterns (for decorative or instructional use)
• Pattern stencils (zigzags, waves, squiggles, and more)
• Geometric shapes (squares, triangles, circles in multiple sizes)
• General shapes (arrows, stars, hearts, squiggles, straight lines)

Also included is an stl with blank templates, providing a ready-made starting point for your own custom stencil designs.

In the slicer of your choice right-click your desired template and select "Add Negative Part" and start creating! Don't forget to upload your custom design as print profile to share it with others.

Compatible with the separate Foldable Architect Ruler model (link), this set is easy to assemble: simply stack your selected stencils on the ruler base and secure them with the included screw.

Whether you’re note-taking, crafting layouts, decorating journals, or working on creative projects, this modular tool brings flexibility, precision, and a touch of fun to your workflow.

Assembly is simple:

Stack the individual scale arms onto the ruler body and secure them with the printable screw — no special hardware required
