NFC Card and Keychain Generator is a Blender add-on for designing 3D-printable housings for NFC chips. NFC chips and QR codes can share socials or a contact card, let guests tap to join Wi-Fi, or trigger automations with a scan, but on their own they don't look great. This add-on wraps them in a printable card, dot, or keychain, and can place a QR backup code or your own logos on the surface.
Shapes are adjustable, with control over height, bevels, rounded corners, and optional magnet slots that use hexagonal or circular cutouts. Import any SVG logo to turn it into an object on the housing, with an inset option for flush multi-color prints, or use the built-in QR generator for links, vCards, Wi-Fi details, or plain text. The NFC cutout is optional, so solid cards and keychains without cavities are possible.
Work happens in the NFC Cards tab of the N-panel: press N in the 3D Viewport, click Prep Scene, set dimensions and cutouts, add a logo or QR code, then export as an STL. It requires Blender 4.2.0 or later and is released under the GPL v3.
