Modelador 3D QR Code Plate & Keychain

About this generator

Modelador 3D QR Code Plate & Keychain turns a text or link into a flat plate or keychain with a raised QR code, from the same small Brazilian modeling studio behind the Modelador 3D Part Generator. You choose the error correction level from L to H, an automatic or fixed QR version, the module size, base and relief thickness, the border and, for a keychain, the ring hole size. A short caption and a one-color image can be added, always outside the code so they never cover it.

Before the download, the tool reads the code back with an independent decoder and compares it with what you typed. The page says plainly that this only checks the code digitally: scanning a printed piece with a phone has not been tested yet, and depends on contrast, light and finish. Codes are static, with no redirect or tracking. The download is a ZIP with the STL, an SVG reference and a technical sheet. The interface is in Portuguese.

Downloads are free once you register a first name and email, and an optional donation is suggested. It suits makers who want a table sign or keychain with a link, Wi-Fi or contact code.
