Matt Reamer and I are always looking for ways to make prototyping better. In a search we found a prototyping tool called the Iron Phone. It was a great tool, but the people that made it didn’t release it to the public. Obviously, we saw this opportunity to help the community that has helped us very much so we created an open source prototyping tool called PAPERPROTO.

PAPERPROTO is a 3D printed phone where UX Designers can perform user testing. The download consists of a 3D printed phone (iPhone 5, iPhone 6, iPhone 6 PLUS, and Galaxy 3) and a designed paper to is fitted for that phone. The paper has a grid layout for accurate dimensions. After user testing take the findings and turn those findings into a functional document.
