Ha! Is that useful for a serious use like scientific study of the content of cigarette smoke, or just a joke about smoking seven cigarettes at once?
(I bet there's more description on the Printables page, but Printables login-walls "NSFW" items, and I'm not going to the trouble of registering for a Printables account.)
Edit: I lied. I went to the trouble of hacking Printables to see the content without logging in. In developer tools, I deleted the modal and backdrop behind the modal, removed the applicable position:fixeds and overflow:hiddens, and found and disabled the filter:blur(...). For those who want to know but don't want to do what I did, more description from the page follows:
