3d print models, parametrically generated.
Blender can run Python... with the app open or headless.
My Blender skills are nigh useless. I know how to describe what I want mathematically with variables/constraints, but I don't know what magical incantation to use to make it appear in Blender... and don't get me started on the hotkeys!
About a year and a half ago, I started writing a script (by hand) to generate a non-trivial widget for personal use (a zigbee controller housing). I sketched my own pencil drawings and wrote about 900 lines of python. It was going really well for a few days, but then life got busy. The file was an experiment (it was named `temporary.py`!!!) that I decided didn't need to die. But I haven't touched it since.
Enter AI... This weekend, after not touching the project for 18 months, I used Cursor to convert my one messy file into a proper, multi-project mono repo for all of my 3d designs, abstract out common Blender commands, scaffold a proper structure for revisions, etc. Then, I was able to use Cursor to finish the design.
I love it! I'm still making my designs (believe me, these aren't 1-prompt creations) but I don't have to worry about the minutiae of Blender's interface and, most importantly, I can use its power.
Side point: I loved it when I could say something like: The body ellipse should have a base whose height is .5 of the body ellipse diameters is .5 the shadow of the body. Using a spline/bezier curve-like profile, it should rise from the floor plane, shrink to 1/3 the size of the body, then grow to meet the ellipse at 1/3 the height of the ellipse, at an angle matching the ellipse's tangent, and parallel to the floor. And it just worked! And I can change the proportions and regenerate the model whenever I want to tweak visual aesthetics.
I have a list of things that I've wanted to model, but the overhead of learning interfaces when I'm already insanely busy is, in a word, prohibitive. This frees me up to build what I can already see clearly in my head, and I love it!
