Interlocking Coaster Pattern – a Fun and Functional Laser-Cut/3D-Printed Project for Your Drinks

Ever wished your coasters were as fun as your drink? Introducing Coaster-locked, the interlocking coaster set that’s part puzzle, part drink accessory, and all-around conversation starter. Perfect for laser cutting or 3D printing, this project brings a touch of whimsy and modular magic to your table. Mix and match the pieces, add some color, and watch your friends try to figure out if they’re coasters or the start of a tabletop jigsaw!

Project Highlights

• Modular and expandable: Create coasters or even wall decor!

• Customizable: Choose different colors or materials to suit your style.

• Easy assembly: Pieces interlock without glue, making it a clean and flexible project.

Material Options:

• Laser Cutting: Wood, acrylic, or MDF sheets (1/8” thickness recommended)

• 3D Printing: PLA or ABS filament in your preferred colors

• Tools:

• Laser Cutter OR 3D Printer

• Design Software (e.g., Illustrator for laser cutting or CAD software for 3D printing)

• Optional: Sandpaper for finishing edges, paint for customisation.

1. Open your design software: For laser cutting, software like Adobe Illustrator or Inkscape works well. For 3D printing, use CAD software (e.g., Fusion 360 or sharp 3d).

2. Create the interlocking shape: Design a shape with interlocking notches, as seen in the reference image. Make sure each side aligns precisely to ensure a seamless connection between coasters.

3. Adjust dimensions: Decide on the size. A standard coaster size is 3.5 - 4 inches in diameter. Ensure that the notches are slightly smaller than the material thickness to create a tight fit.

For Laser Cutting:

1. Export your design as a vector file (SVG or DXF).

2. Load it into your laser cutter software, adjusting settings based on material (wood or acrylic).

3. Cut out a few pieces to test the fit.

For 3D Printing:

1. Export the design as an STL file or 3mf.

2. Load into your slicer software, adjust print settings, and print a sample to check interlocking functionality.

Interlock the pieces: Test to see if the pieces fit well. Adjust your design if necessary.

Customize your coasters: Paint, sand, or varnish to add a personal touch. You can even add a layer of cork underneath for extra grip.

Create additional pieces to form larger patterns. Arrange them as wall decor, placemats, or even a modular table runner!

This interlocking coaster project is a fun exploration of pattern-making with practical applications. Whether you’re new to laser cutting and 3D printing or an experienced designer, this project allows you to bring your creativity to life in a tangible way. Enjoy your personalized, functional artwork!
