Fresh out of the printer: the Hearthstone USB Keychain NFC Access Chip. 🖤🖨️ 3D-printed, solid, and stylish — carrying the Hearthstone swirl with that iconic look. But here’s the twist: it’s not just a keychain. Inside, it holds my NFC chip, and with just a tap I can unlock my door. Now I’m debating whether to leave it raw for that clean 3D print look… or paint it to make it truly pop. Either way, it’s already practical, geeky, and a bit magical. ⚡ #Hearthstone #3DPrinting #NFC #DIY #Maker
