About this Product
These are 3D models of the Adafruit Flora microcontroller and accessory modules. They are available for download to help you create a 3D mockup or case for your design. They come with a detailed texture map, but this is only for rendering, since the parts are too thin to produced with Full Color Sandstone (unless you are a huge Flora fan, and want to print them at 4x scale).
