Soundwave Keychain (audio → keychain)

🎙️ Turn your voice into a keychain - 3D print the sound of a moment

Record a few seconds - “I love you”, a laugh, a pet’s bark, a baby’s first word - and this turns the sound wave into a small, two-color keychain you can carry everywhere. Every wave is unique, because every voice is.

✨ Make it yours (free generator)

- 🎤 Record or upload — a few seconds from your mic, or drop in an audio/song file

- 🔒 Private by design — the audio is processed entirely in your browser; nothing is uploaded

- ✂️ Trim to the exact moment with a simple slider — cut the silence, keep the magic

- 🌊 Wave styles — classic bars, slim bars or a smooth filled waveform

- 🔑 Keychain hole — on the side or tucked in the top corner

- 🅰️ Add a label — a name or date under the wave, four fonts, two sizes

- 🎨 Real Bambu filament colors — pick base + wave from the actual PLA palette (spool codes shown), so what you preview is what you print

🖨️ How to make yours
 

1. Go to https://tanskylab.com/soundwave

2. Record your sound (or upload a file) and trim it.

3. Choose the wave style, colors, size and the keychain hole.

4. Generate → download the ready-to-slice 3MF → open in Bambu Studio → print.

Base plate and the raised wave are set up as two colors with the filament change already placed - just print, swap the spool when prompted (or let your AMS do it).

⚙️ Print notes

- Small and fast: ~70 × 30 mm, ~1.6 mm thick, roughly 30 minutes to print

- Two colors, one filament change - works great without an AMS (single pause & swap)

- Prints flat, no supports; rounded corners and a clean keychain hole

- 0.08 mm layers for a crisp wave
