Rachio Wire Junction Box

I had a pair of sprinkler cables coming into my brand new Rachio 3 (https://www.amazon.com/Rachio-Smart-Sprinkler-Controller-8-Zone/dp/B07CZ864Y9/ref=as_li_ss_tl?s=aps&ie=UTF8&qid=1530457220&sr=1-1-catcorr&keywords=rachio+3&linkCode=sl1&tag=62616285-20&linkId=9f21858e911bfe63ff61ca59730bfe14) garage controller, and that just wouldn't do. I needed to clean it up, so there was no better way than making a simple junction box for the low voltage wires going out to the valves.

Where I previously had two heavy black multi-conductor cables going in, it has slimmed down to one. This also remedied the problem where one of the cables wasn't long enough to reach where I needed to mount the Rachio.
I designed it around this wire (https://www.amazon.com/Rachio-Smart-Sprinkler-Controller-8-Zone/dp/B07CZ864Y9/ref=as_li_ss_tl?s=aps&ie=UTF8&qid=1530457220&sr=1-1-catcorr&keywords=rachio+3&linkCode=sl1&tag=62616285-20&linkId=9f21858e911bfe63ff61ca59730bfe14), though I don't recommend buying 500 feet
