I got a question. I'm wondering if I can just have only the relay hooked up into the loop, since I'm going to have Octopint controlling the relay (and hence, controlling the printer)

Simple, but elegant solution. Wiring diagram attached. Use it if you want :)

Great ! Thanks !!!
It is indeed easier to read.
I will add it to the Thing Details

Nice one.

Mine does not require any fiddling with electricity, but your's a nice one anyway :D

Your design is interesting, but I like the convenience of an electric solution rather than a fully mechanical one.
It is also much more discreet than your somehow bulky wire.
Anyway, people will choose the solution they prefer.

Edit: Nevermind, I just reread your post and you have it already covered.
