Mash buttons anywhere, anytime. A pocket-sized gamepad-inspired fidget that clips right to your keys.

Channel your inner gamer with this compact fidget keychain styled after a classic controller's four-button layout. Each colorful button presses with a satisfying magnetic force — perfect for stress relief, focus, or just keeping your thumbs entertained between actual gaming sessions. Stuck in a boring meeting? Mash some buttons. Waiting in line? Mash some buttons. You get the idea.

🎮 Gamepad-Inspired Design Four vibrant buttons in classic controller colors arranged in the familiar diamond pattern. A nostalgic nod to the controllers we all grew up with, sized down to fit in your palm.

🎨 Multi-Color Without an AMS The buttons are printed separately, so you can use up filament scraps and customize the color scheme however you like — go retro, go neon, or match your favorite console's palette.

🧲 Magnet Assembly Made Easy This model uses 6x3mm magnets to give each button that signature satisfying repelling force. To make assembly painless and ensure correct magnet polarity every time, I highly recommend pairing this with my magnet applicator tool:

🛠️ Assembly Helper (separate print profile) I've also included a dedicated assembly helper jig as a separate print profile on this model page. It holds the components in position during magnet seating and glue-up so everything lines up cleanly. Print it once and you'll thank yourself on every build.

📦 What You'll Need

• 6x3mm neodymium magnets (quantity to match your build)
• A drop of CA glue for securing magnets
• A keyring/split ring
• Filament in your choice of button colors

📝 Assembly Notes Magnet polarity matters — mismatched magnets will attract instead of repel. The applicator tool linked above takes the guesswork out and makes this a quick, painless build. All magnets for this model should be place with the same polarity, even the the Assembly helper model.
