I designed a tiny collapsible laptop stand that fits in your pocket and weighs less than a AA battery. It props up the back of your MacBook (or most laptops with a rear lip), and also works as a phone/tablet stand. After dozens of prototypes, I landed on a form that prints fast, folds flat, and actually feels stable. Site is live at https://floatystand.com Feedback welcome!

Also if you have a 3d printer, the files are available for free, just check the FAQs of the website.
