Make-A-Coin: Premium Custom Event Tokens, Decision Makers & Keepsakes (Parametric)

Make your next big event unforgettable with a fully personalized, premium-weight custom token.

Most 3D printed coins feel light and cheap. Make-A-Coin is different. Using a cleverly designed internal cavity, this parametric model can encapsulate a standard heavy steel washer, giving your custom tokens the satisfying heft and "clink" of a real, high-quality challenge coin. Or print the included washer for a similar feeling without the added cost.

Whether you are designing elegant wedding favors, hilarious stag do keepsakes, or unique business tokens, you can customize every single aspect directly in MakerWorld—no CAD software required!

Endless Ways to Celebrate

Ditch the generic party favors. Create something your guests will actually want to keep:

• Weddings & Save-the-Dates: Print the couple's initials on one side and the wedding date on the back. Serve them as elegant table favors!
• Stag & Hen Dos (Bachelor/ette Parties): Mint custom "Drink / Pass" tokens, VIP access coins, or embed a funny inside joke for the squad.
• Baby Showers & Gender Reveals: Create custom weight/date keepsakes or "Boy / Girl" reveal coins.
• Tabletop Gaming & D&D: Forge heavy, satisfying currency, inspiration tokens, or faction markers for your campaign.
• Geocaching & Business: Leave behind a premium signature token, or hand out heavy-duty "business card" coins that clients won't throw away.
• The Classic Decision: YES / NO (Settle any basic argument instantly).
• The Dinner Dilemma: EAT IN / EAT OUT (End the nightly "I don't know, what do you want?" cycle).
• The Gamer's Choice: ONE MORE GAME / GO TO BED (Flip at your own risk).
• The Kids' Reward: ONE CHORE PASS / 30 MINS EXTRA SCREEN TIME (A tangible treat they can earn and trade in).

Premium Engineering & Accessories

• The "Heavy Core" Snap-Fit: The coin is designed around a standard heavy washer (Outer Diameter: 39.55mm, Thickness: 2.35mm). Simply drop the washer into the rim, press the two custom faceplates in, and enjoy a satisfying, glue-free mechanical snap-fit.
• The “Medium Core” Snap-Fit: Print the included washer while you’re printing your coin anyway.
• The Display Easel: Want to show off your token? Toggle on the Classic A-Frame Easel to print a perfectly angled display stand.
• The Keychain Bumper: Turn your event token into an everyday carry! Toggle on the Latching Sandwich Cage to print a rugged, snap-together protective bumper that attaches straight to your keys.

How to Customize in 3 Easy Steps

Using the MakerWorld Customizer, you can make this coin entirely your own:

1. Choose Your Edge: Select from a smooth edge, a classic reeded edge, or type in your own custom edge text (e.g., "SMITH WEDDING 2026 * ").
2. Design the Faces: Choose whether you want to use Text (up to 3 lines per side) or an Image (upload your own 2D graphics).
3. Upload Your Art: If using images, simply upload your 2D logo or icon. Note: Heads requires a .png file, and Tails requires a .svg file (ensure your SVG uses "paths" and not live text or embedded images).

Infinite Possibilities: Custom PNG & SVG Reliefs [Parametric Mode]

The true magic of Make-A-Coin happens when you move beyond simple text and bring your own designs to life. By switching to "Image Mode," you can transform any 2D graphic into a high-detail 3D sculptural relief, allowing you to mint virtually any coin or token you can imagine.

• Heads side (PNG): Upload any high-contrast .png file to generate a stunning front-face relief.
• Tails side (SVG): Use a .svg vector file for the reverse side to complete your unique design.
• Ultimate Creative Control: Whether you are minting custom family crests, corporate challenge coins, iconic gaming symbols for your D&D sessions, or unique reward tokens for your kids, the possibilities are limited only by your imagination.
• High-Resolution Surface: Because the system prints the face plates completely flat on the build plate, your custom PNG and SVG graphics can render with incredible detail. 
  • Use your 0.2 nozzle to print these if the detail seems too fine for your 0.4 nozzle.

Quick Tip for Success: To ensure your custom images are perfectly centered, remember to manually enter your source image's pixel dimensions (e.g., 512x512) into the customizer so the script can accurately auto-scale your design.

Assembly Instructions:

1. Print the Rim and the two Faces flat on your build plate.
2. Grab a standard metal washer (Dimensions: [39.5mm x 2.35mm) or use the included printable washer
3. Sandwich the washer between the two printed faces.
4. Press them firmly into the rim until you feel the locking nubs click into place. No glue required!
