Each of the related intents above marries with a function within a Lambda function hosted at Amazon AWS.
Most of the actual functionality is provided via the wonderful API within OctoPrint.
It was necessary to write and host a firewall proxy to allow the inbound Internet-based traffic to be proxied to/from the printer itself. I wrote this in Node.js and it's called octo-proxy. My firewall then forwards an emphemeral port to this Raspberry Pi Zero W computer which runs the proxy.
Teaming this with a TP-Link Smart Plug, I am also able to power ON/OFF the entire printer itself remotely via the Amazon Alexa interface.
I intend to create a website which allows people to introduce their own 3D printers as a profile and then remotely-control them via an authenticated console. Obviously, each person would need their own proxy but I imagine generating and selling these as a low-cost add-on to the otherwise (assumed) free service.
I'll also need to proxy the printer's webcam service, to stop/start the webcam, etc. But the functionality at the moment is rather good so far.
