Hey Producthunt,
A couple of years ago I launched Sketchsheets - a free resource for printable device templates. Since then I've received lots of feedback from designers and students around the world, and have been overwhelmed by requests for new devices and templates. Over the last few weeks I've redesigned, and simplified, the site - adding loads of new templates for the latest devices and platforms.
Looking forward I'm looking at making it easier for people to submit their own templates to the site for others to use. At the moment you can do this via a pull request on GitHub.
