Requirements

macOS 14 Sonoma or later. Apple silicon and Intel. Renders are previews of a model, not photos of a print: add a real photo of the item to each listing. It renders files you already have; it doesn't make models. Current version: 1.0.

Privacy

Your models never leave your Mac. Printreel opens only the files you choose and saves only where you choose. The only network requests are the license check with Gumroad and checking for updates.
