The Convex is a geometric ceramic plant pot with a center drainage hole and a matching saucer, and it was the first thing we ever made by asking a laser 3D printer to essentially print a piece of mathematics. The mold cost roughly two thousand dollars to produce, which at the time felt like a serious investment in a very specific idea and would now cost about thirty-five dollars at a copy shop on a slow Tuesday.We try not to think about that too often. The pot is still beautiful. The mathematics still work. The two thousand dollars is gone and is not coming back, which is also a piece of mathematics, just not the fun kind. The drainage hole keeps roots healthy, the saucer keeps the surface underneath dry, and the curve does the rest, catching light along an edge no potter's wheel could ever reproduce.
