it is interesting that the video demo is generating .stl model. I run a lot of tests of LLMs generating OpenSCAD code (as I have recently launched https://modelrift.com text-to-CAD AI editor) and Gemini 3 family LLMs are actually giving the best price-to-performance ratio now. But they are very, VERY far from being able to spit out a complex OpenSCAD model in one shot. So, I had to implement a full fledged "screenshot-vibe-coding" workflow where you draw arrows on 3d model snapshot to explain to LLM what is wrong with the geometry. Without human in the loop, all top tier LLMs hallucinate at debugging 3d geometry in agentic mode - and fail spectacularly.

Hey, my 9 year old son uses modelrift for creating things for his 3d printer, its great! Product feedback: 1. You should probably ask me to pay now, I feel like i've used it enough. 2. You need a main dashboard page with a history of sessions. He thought he lost a file and I had to dig in the billing history to get a UUID I thought was it and generate the url. I would say naming sessions is important, and could be done with small LLM after the users initial prompt. 3. I don't think I like the default 3d model in there once I have done something, blank would be better.

We download the stl and import to bambu. Works pretty well. A direct push would be nice, but not necessary.

Thank you for this feedback, very valuable! I am using Bambu as well - perfect to get things printed without much hassle. Not sure if direct push to printer is possible though, as their ecosystem looks pretty closed. It would be a perfect use case - if we could use ModelRift to design a model on a mobile phone and push to print..

proper sessions page is live: https://modelrift.com/changelog/v0-3-2

let me know how it goes!

If you want that to get better, you need to produce a 3d model benchmark and popularize it. You can start with a pelican riding a bicycle with working bicycle.

I am building pretty much the same product as OP, and have a pretty good harness to test LLMs. In fact I have run a tons of tests already. It’s currently aimed for my own internal tests, but making something that is easier to digest should be a breeze. If you are curious: https://grandpacad.com/evals

building a benchmark is a great idea, thanks, maybe I will have a couple of days to spend on this soon

Yes, I've been waiting for a real breakthrough with regard to 3D parametric models and I don't think think this is it. The proprietary nature of the major players (Creo, Solidworks, NX, etc) is a major drag. Sure there's STP, but there's too much design intent and feature loss there. I don't think OpenSCAD has the critical mass of mindshare or training data at this point, but maybe it's the best chance to force a change.

I was looking for your GitHub, but the link on the homepage is broken: https://github.com/modelrift

[jetter]

right, I need to fix this one

[storystarling]

yes, i had the same experience. As good as LLMs are now at coding - it seems they are still far away from being useful in vision dominated engineering tasks like CAD/design. I guess it is a training data problem. Maybe world models / artificial data can help here?
