The actual geometry would be slightly different (the projected outline of the belt would curve as it passes around each roller) but not in a way that prevents the surface from being constructed like this.\n\nhttps://media.mathstodon.xyz/media_attachments/files/113/666/371/063/884/444/original/05fd75223ea3a74c.png",
