Unfolder for Mac – A 3D model unfolding tool for creating papercraft

I like the clean design of the landing page. I downloaded it and started the app and it needs an OBJ file to even do anything, so I wasn't able to play with it at all.

It would be cool if it included sample OBJ files to entice me to find my own later. Otherwise I feel like I just hit a wall immediately in the app will probably not try it again.

This is great - reminds me of the golden age of cool little MacOS apps

So, like Pepakura? https://pepakura.tamasoft.co.jp/pepakura_designer/

Mac only. Is there any reason this couldn't be a web app? And seems pretty restrictive to just have one platform, a desktop Mac.
