3D Printable Models
The user can read this book and understand the concepts from the photographs of 3D printable models alone. However, since many models are puzzle-like, we encourage the reader to print the models on any consumer-grade filament based 3D printer. The models are available for download in a freely-available open source repository. They were created in the free program OpenSCAD, and can be 3D printed or modified by the student in OpenSCAD to learn a little coding along the way.
A note about the EPub file...The Make: Trig epub3 digital download that comes as part of this package (along with a PDF version) works with screen readers that can read math, such as the Thorium epub reader.
After you have the book open in Thorium, turn on MathJax functionality, which in turn reads MathML. In the current version of Thorium (2.2.0) check the box to enable MathJax at Settings > Display > MathJax. These settings are only available after you have opened at least one book in Thorium.
If you are using a separate screen reader program to interface with Thorium, you might need to add a plugin for it to be able to read MathML correctly. This epub file been optimized for screen readers and accessibility for our visually impaired readers.
