Pick the iPhone 16 Pro Max or iPhone 16 model, print a name or your logo SVG file, then download a 3MF or STL to print. The case prints back-side down with no supports; the rim rises slightly over the screen edge to hold the phone, with openings for the camera, the Camera Control button and the charge port.
The flat style takes 2 colours with the art in a third colour level with the case — it needs a multi-colour printer; the engraved style prints in one. The SVG file stays on your device, is sent nowhere and never appears in the copied link.
The fit numbers (the gap around the phone, the rim depth) come from other designers' practice; nothing has been printed and fitted to a real phone. Passed simulation and slicing in OrcaSlicer only.
This tool is for learning and personal use. It is not endorsed by the phone maker; a printed case may not fit or protect. All risk is yours.
