For creating models: Blender is tops, openSCAD and Open CAD are good but a lot more technical.

For basic stuff, most slicers have objects and negative connects that you can sculpt I’ve something functional. I made a basic model last week for a thing I needed only in the slicer.

For slicer software: sometimes 3d printer brands customize a more common software to tune it to the specific machine. I’m a fan of Orca, but Cura and PrusaSlicer are also really good.

All of these are available as FOSS on Linux.

Immutable?

Well, I’m not entirely clear on what snapshots are so you’re doing better than me and I haven’t been on windows in a few years now lol!

Idk, but my install offers a version rollback at the bootloader. Had a weird graphics issue after an update, so I just used an older version for a week or so till a new update fixed it.

This verse has been interpreted in the Left Behind series IIRC too.

They religious nutters will say it was God intervening, but the evangelicals will mysteriously forget that the Bible says that The Antichrist will miraculously recover from a head wound.

Reading this is an actual cognitive hazard.
