I wanted to put a logo on something made with a 3D printer.
In October 2025, I brought the idea to Kimiko-chan. Kimiko-chan is the name I gave ChatGPT.
I wanted something friendly and approachable. But adding color would be difficult for this project. Instead of using different colors to show the design, I wanted to express it through raised and recessed shapes on the surface.
The design had to become a physical feature on the object, so there was more to consider than how it looked on a screen.
As we discussed it, I made the requirements more specific.
First, a circle, about three centimeters across. A symbol would sit inside it, with flowing water in the background.
Round, approachable, with a sense of flowing water. So far, we were talking about the look of the design.
Then came a request particular to making it three-dimensional.
How far should the logo stand above the surface?
The height I specified during the discussion was 0.4 millimeters. That meant the logo would rise that much above the surrounding surface.
I also requested three sizes: 30, 40, and 50 millimeters in diameter.
An idea for a circle about three centimeters across had turned into a discussion of three diameters and a very precise little bump.
Kimiko-chan supplied code describing the shape. Our exchange connected my requests for a circle, particular sizes, and a raised design to a concrete proposal.
Looking back, my part in the conversation went beyond describing the mood I wanted.
What would the logo go on? How did I want it to appear if color was difficult to use? How large should it be, and how high should it rise? Those were requirements I supplied too.
A request to “make it look good” gradually became a set of conditions for a physical object. That was the interesting part of this conversation.
I left “friendly and approachable” rather open-ended. The bump, though, had to be 0.4 millimeters.
This story looks back on a logo-design discussion on October 31, 2025. It covers the stage where I specified the shape requirements and received a code proposal.
