Marius Kintel is the primary author and maintainer of OpenSCAD. He is a software engineer with more than 20 years of professional experience in diverse fields such as 3D visualization, physical computing, manufacturing automation, and cloud computing. In 2007, he became involved in the RepRap project out of an interest in learning electronics and the opportunity to transfer his knowledge of 3D graphics into the creation of tangible objects. Together with the rest of the local RepRap team at the Metalab hackerspace in Vienna, Austria, OpenSCAD was created out of a need for an open-source multi-platform design tool more suitable for 3D printing. The project was adopted by the maker community at large, and has since grown to become one of the most popular open-source 3D modeling tools for 3D printing.

Justin Gohde has been teaching Math and Computer Science for more than 20 years. He is the Head of Computer Science at Trinity School in Manhattan, New York where he oversees the Computer Science curriculum and programs, including a Design Lab makerspace with a wide collection of rapid prototyping tools for supporting Computer Science, Robotics, and other STEAM-focused projects.
