A seashell you can plant: a full-bodied nautilus whorl standing on a sliced flat base, with the plant rising out of the shell's open mouth. I kept the spiral deliberately irregular — one side fuller than the other, uneven growth lines — so it reads like a shell you picked up on a beach, not a math exercise.

Prints in a single PLA color (mine is white). The whole read is geometry: spiral ridges and growth lines catching the light, so there's nothing to paint.

About 133 × 128 mm at the base and 150 mm tall. Flat, stable underside. The mouth opens into a deep soil cavity, and a smaller second pocket beside the mouth takes one more tiny succulent. There are no drainage holes in this version — I plant mine with a gritty, fast-draining mix and water sparingly, the way you'd treat a cachepot. If you want drainage, it's easy to add a couple of holes in your slicer before printing. Indoor pot.
