I was inspired by at least one other PVC sprinkler instructable to create my own, larger version. What you see here is the finished product in all its glory. My wife likes to refer to it as the "Sprinkle-Master 5000". I'm not exactly sure why.
I'm submitting this instructable as part of the dadcando contest for your enjoyment. Feel free to vote.
Step 1: Design
The inspirational instructable for this creation was basically an upside-down squared U shape. It looked like a lot of fun, but was two dimensional. I wanted to make something more three dimensional, so I thought up a cube design.
My design process was all in my head, and these sketches were done just for this instructable, but are a good representation of what I would have done if I had put pen to paper.
The first of the three sketches are a top down design. You are floating in the air, looking down on the square top, and you see the legs going from each corner down to the ground. Next comes an "isometric" (quotes added because the sketch is really bad) view, from one top corner in. The last sketch is a closeup of the original plan for the corner. It didn't work out like this, but in the end, I'm glad it didn't.
