Did I do it?
I originally thought I'd have to rotate the thingy around the 3 piston, but I arbitrarily gave myself enough space such that I made it work even without that. I'm also really glad none of the glyphs to copy the Dry Air (which were added after creation of Dry Air) messed with the initial production of Dry Air. Wasn't fully intentional, but I was glad to not have to perform such finagling.
I'm going to pay for having a well-behaved looping solve in secondary, and I'll pay further in layout.
But I got a noncompetitive min primary. And that alone justifies the solve. With this...I catch up to the people walking in footsteps.
