alt Hacker NewsI love it. I do 3D printing as a hobby, but I really dislike the design phase. I usually need simple shapes: boxes or enclosures for electronics. I can find most of what I need on Thingiverse and similar platforms, but there’s always that 20% of things I need to design myself to adapt them to my specific needs.
SketchUp 8 was the easiest software for me to learn, and it just clicks with me. I really wanted to learn FreeCAD, but there's something about the way it works that I just can't get along with, so I keep going back to SketchUp.
Later, I tried all the alternatives: Onshape, Fusion, Tinkercad, and the new SolidCraft, but SketchUp still feels so simple and intuitive to me.
I've had better luck with OpenSCAD for simple things, and I still need to try it out with LLMs. That's on my TODO list!

I've had some good luck with using Claude (Opus 5.5) for making models for 3D printing just by describing the thing I want (with measurements if you've got em) and having it create an OpenSCAD file.
It's also weirdly good at taking an existing STL file of a functional print and writing some python to modify it.
One example was a badge holder that I liked the design of, but only held 2 badges. I wanted 3, plus a slot on the back for a key. Gave it measurements of the key, it grafted a key slot on the back, and added the third badge slot. In typical 3D printing fashion, of course I had to print like 5 iterations of the thing until the sizing of everything actually worked.
I have the same problem with FreeCAD: I really want to uae FreeCAD. But after some weeks or months I cannot even remember simple things like how to add a new object (or hole) to a face of an object.
