I knew it would only be a matter of time until we saw MySensors custom injected molded components!
I think if you made a box that could fit the Easy / Newbie board (~50x50cm) plus radio and 2AA batteries, you would probably sell a lot of them! I know I would buy some of those...
Reporting back: I have my BambuLab X1C printer setup and have printed with it for about a week. It's fantastic: it's fast, and the prints come out perfectly every time. Truly an appliance: it works with only minor setup straight out of the box. I'd say it's a quantum leap better than my Prusa MK3S, which I guess I should try to sell while it still has value.
