This skill communicates with the 3D Printer Host Gadget. The Gadget is a DIY electronics project whose instructions can be found here: https://www.hackster.io/Milesnash_/3d-printer-monitoring-with-alexa-and-arduino-024292 . The skill currently only supports functionality for monitoring my printer. The creation of a skill to monitor your own printer is covered in the guide linked to above. This skill serves as an example of the functionality enabled by constructing a 3D Printer Host and custom Alexa skill. For more information follow the link above.
