Halloween Click Keychains | 3D Print 3MF Swappable Letter & Icon Set

Build your own spooky keychains — and change them whenever you like. Halloween Click Keychains is a 3D-printable keychain system with swappable click-in keys. Print the bases once, print the letters and icons you love, then click them together to spell anything: BOO, SPOOKY, or a custom name for every trick-or-treater. Want a new look? Pop the keys out and rebuild — no glue, no hardware, everything is 3D printed.

The Witch's Brew color combo mixes indigo purple and bamboo green keys with pumpkin-orange inlays for a look that screams Halloween.

What You Get — 3 Print-Ready 3MF Project Files

• LETTERS: full alphabet A–Z plus Ñ (27 letters) in BOTH key colors (purple and green) — 54 letter keys with bold orange display lettering
• ICONS: 42 spooky icons (ghost, skull, spider, black cat, crow, witch hat, broom, spell book, potion, full moon, lightning and more), each in purple AND green — 84 icon keys
• BASES: 7 keychain bases from 1 to 7 keys, each in two versions — with the print-in-place click system and without it. Keyring loop built in.

How It Works

1. Print the bases and the keys you need
2. Click the keys into the base — the print-in-place click system holds them firmly
3. Swap keys anytime to spell a new word, mixing letters and icons freely
