📐 The ultimate customizable 2D shape & tag generator!

Are you a teacher looking for geometric manipulatives for math class? A crafter needing perfectly sized stencils? Or maybe you just need to generate a bunch of blank custom keychains? This fully parametric OpenSCAD generator instantly creates 15 different mathematically perfect shapes at any dimension you require.

⚙️ Customizer features:

• 15 classic shapes: Instantly render a circle, square, triangle, pentagon, hexagon, octagon, star, heart, cross, ellipse, ring, crescent, capsule, or trapezoid.
• Mass batch generation: Select All Shapes from the dropdown to instantly generate a perfectly spaced layout of all 15 shapes on your build plate at once!
• Infinite sizing: Enter your exact width, length, and thickness.
• Dynamic hole placement: Easily convert any shape into a keychain, luggage tag, or binder-ring flashcard by enabling a utility hole perfectly positioned at the center, top edge, or corner.

🧠 Behind the design (For makers & moderators)

To provide the absolute fastest rendering performance, this model generates 2D vectors and linearly extrudes them into 3D manifolds, avoiding slow 3D booleans whenever possible.

The shapes are dynamically bounded using mathematical min and max limits. For example, if the user inputs a corner radius larger than the shape itself, the algorithm dynamically clamps the radius to prevent the geometry from collapsing or inverting inside the slicer. The massive All Shapes layout is generated using a nested looping array that calculates a localized offset grid while reading the individual properties of all 15 different profiles simultaneously.

🖨️ Print settings:

• Material: PLA is perfect for educational tokens and tags.
• Layer height: 0.20mm for speed.
• Supports: STRICTLY NONE. The shapes print entirely flat on the bed.
• Top surface: Enable Ironing in your slicer to give the flat tops of the shapes a beautifully smooth, injection-molded look!
