First, the authors would like to acknowledge the hard work and significant efforts put in by so many folks operating behind the scenes to make this book happen. As technical reviewer, Miro Hrončok made many, many insightful and meaningful contributions to the evolution of each chapter. His feedback and advice were well seen, well considered, and well appreciated. We’d also like to thank everyone at No Starch for their remarkable patience, dedication, and guidance throughout the book writing process. In particular, we’d like to acknowledge and thank Bill Pollock for agreeing to publish one of the first books about OpenSCAD, Tyler Ortman for getting the ball rolling, and finally Jill Franklin and Dapinder Dosanjh for getting the project back on track and over the finish line.

Justin would like to thank the many Trinity students and faculty who helped prototype the core lessons and activities presented in this book—in particular, colleagues Noah Segal, Mark Schober, Rob Newton, Jean Kim, and Andrew Rose for their thoughtful contributions to the conversation. Much gratitude is owed to Chris Martin, for initiating scores of London chats on the pedagogical importance of using starting points to motivate self-reflective, inquiry-based learning. And, finally, an infinite debt of thanks is due to Yasuho Mori due to her eternal patience, persistent optimism, and steadfast support.

Marius would like to thank all contributors and users of OpenSCAD. In particular he would like to thank Torsten Paul, who has been instrumental in keeping OpenSCAD moving forward over a number of years. Also, thanks to the Metalab hackerspace in Vienna, and all the diverse and colorful individuals that frequent the space, for creating an inspiring environment where projects like OpenSCAD can evolve. Special thanks go to Claire Wolf for single-handedly cranking out the initial codebase for OpenSCAD and Philipp Tiefenbacher for being an amazing project partner and visionary who helped bootstrap all the activities that eventually became OpenSCAD. And finally, to Jane Tingley for her continuous support, encouragement, and unwavering belief.
