A 3D-print project stalled for 18 months, finished with Cursor
A messy, roughly 900-line Blender script, abandoned. Cursor turned it into a proper repo for all their 3D designs, then built shapes they described in plain language. "These aren't 1-prompt creations", they add.

Result Now a mono repo for all their 3D designs
“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”
Spotted: found in the wild. Details are as reported by the source above and have not been independently verified.
What they did
Eighteen months after abandoning a roughly 900-line hand-written Python script for a parametric zigbee controller housing, they used Cursor to convert the single messy file into a proper, multi-project mono repo for all their 3D designs, abstracting out common Blender commands and scaffolding a structure for revisions.
How it went
They were then able to use Cursor to finish the design itself, describing shapes mathematically in plain language and having it just work, letting them regenerate the model whenever they want to tweak proportions. They’re clear the designs still take real work: “believe me, these aren’t 1-prompt creations”.
Try it yourself with Cursor
Take an old, messy personal script you abandoned months or years ago and hand it to [your coding agent], asking it to restructure the project into a proper repo (or mono repo), extract common helper functions, and scaffold a maintainable structure. Then keep working in plain language with it to finish the actual feature.

A data scientist tried Cursor on a real project. Prototyping, code completion and commenting went well, but pandas code kept failing and it deleted a bunch of data files.
A 42k-line site with packages to upgrade: 19 easy, 42 medium and 14 hard, by Cursor's own sort. Cursor cleared the easy and medium ones, then a background agent moved it from Remix v2 to React Router v7.
A MongoDB-like database for a hobby project, written spec-first by Claude, Kiro, Qwen Coder and Cursor. They read zero lines of the code and checked it through tests. The first version took about two weeks, part time.

A huge, convoluted codebase they'd taken over. One prompt in Cursor's Plan mode found the bugs and planned the fix, then the agent made it, where the client's previous team hadn't.
