His entire point is trying to get stuff working (even for a few seconds) using cheap hobbyist printers and not requiring skills in metal fabrication or any special equipment.

With that goal in mind, I think he does incredibly well on his projects.

Of course other people can do better with CNCs and years of engineering/fabrication skills. That's like saying it's not worth playing with DIY "anything" because other people can do it better than you.

Yeah. And if the maker here does a few more iterations of the engine it should become much more refined. :)

it works in the sense that a thrown brick flys.

Definitely not. A turbojet is not something you can make work by just brute force.

This isn't a usable turbojet engine, but it did work, for a short while, and that is a real achievement.

Then the news article should have mentioned that point.

But the news article very much arouses the impression that that is not his point, that his point is something other, and that he succeeded at said other point, he never endeavored to succeed at.
