According to the article / is not in basic alphanumeric alphabet anyway?

The article has an off-by-one error. There are 45 characters in the basic alphanumeric alphabet, and / is the missing one.

Is it though? Looks and feels like AI slop on openscad

Indeed, and what worries me is that it might pull resources away from OpenSCAD or similar projects for something that, I imagine, won't be maintained.

What resources will it pull away if it’s unmaintained?

Contributors to alternatives.

AI Slop, yes. OpenSCAD, no. You can read the package file and see the dependencies. It is based on three.js and a couple of boolean-related plugins, and then the LLM wrote a text-based STL export function.
