▶️ What is it?

A 3D-printed keychain shaped like a Play button — the universal symbol for video content. Designed with a recessed pocket to hold a standard 25mm coin-type NFC tag, it doubles as a smart keychain that can instantly open your YouTube channel, showreel, Vimeo portfolio, or any URL when tapped against a smartphone.

Built for videographers, filmmakers, content creators, and anyone in the video industry who wants a quick, memorable way to share their work face-to-face.

🎬 Use cases

• Tap to open your YouTube channel or latest video
• Share your showreel at networking events or film festivals
• Link to your Vimeo portfolio during client meetings
• Point to your video production website or booking page
• Hand it over as a conversation starter — people always ask about it

🔧 How to add NFC functionality

The model has a recessed pocket on the back sized for a 25mm coin-type NFC tag. After printing:

1. Download a free NFC writing app (e.g. "NFC Tools" on Android/iOS)
2. Copy the URL you want to share (YouTube, Vimeo, website, etc.)
3. Use the app to write the URL to your NFC tag
4. Drop the tag into the pocket on the back of the keychain
5. Optionally seal with a small drop of super glue or epoxy for durability

You can reprogram the tag anytime — swap between your latest project, your channel, or a specific video. The keychain also works perfectly as a decorative piece without an NFC tag.
