Customisable Tile Style Keychain Generator

⭐ Customisable Tile-Style Keychain Generator

Create your own personalised tile-style keychain with this easy-to-use OpenSCAD customiser!
Perfect for backpacks, school bags, luggage tags, pet tags, party favours, kids’ accessories, or custom branding for craft sellers.

This customiser builds a compact, playful “tile block” aesthetic using connected character tiles, each with a raised letter — just like a miniature version of your tile sign.

🔧 Main Features

🧱 Tile-Block Letter Design

Your keychain is formed from individual tiles that join together seamlessly, one per character.
This creates a bold, modern look that prints cleanly even at small sizes.

🔗 Integrated Keyring Loop

Choose whether to include a keyring loop and which side it appears on (left or right).
The loop is blended smoothly into the tile body for added strength and durability.

🎨 Two-Colour Preview

Choose separate preview colours for:

• Base tiles
• Raised letters 

Perfect for two colour keychains, or even paint each character a different colour!

✏️ Built-In Font Options

Includes a curated selection of ~20 MakerWorld-safe fonts across a wide range of styles:

• Chunky / Bold
• Rounded / Friendly
• Modern Sans-Serif
• Classic Serif
• Handwritten / Playful
• Pixel / Blocky / Retro
• Futuristic / Tech-Style
• Decorative / Themed

This allows you to match your keychain to any personality or aesthetic.

🧩 Puzzle-Style Tile Connections

Optional puzzle-style interlocking tabs give the keychain a fun, connected appearance.
You can also switch them off for a clean, uniform bar.

🔲 Adjustable Dimensions

Customise every aspect of the design:

• Tile width & height
• Corner radius
• Puzzle tab radius
• Base thickness
• Raised letter height
• Font size

This lets you create tiny backpack tags, chunky key fobs, or stylish bag charms.

🟦 Optional Smooth Edge Fillet

Enable a subtle rounded-edge effect to soften sharp edges and give the keychain a premium feel.

🖨️ Print-Friendly Geometry

Designed to print flat with no supports required.
Raised letters print crisply even on smaller nozzles, making it easy to achieve clean multicolour effects.
