There's a lot of files running around with existing models for common projects, so you probably don't need to design your own enclosures a lot of the time unless you want to.
And printers have gotten cheap, like $99 gets you a jumping off point into the hobby.
The board in the article is $13.49 ( https://www.amazon.com/dp/B072HBW53G ). If you could get an enclosed, complete thing for $20, including the board and whatever you need for it to run, that'd be much less of a PITA than "brand new hobby" or "find someone to 3D print stuff for me locally and deal with that whole hassle".
solving something would be like $700 calibrated out of the box, like the old prusa 3 something or the bambu p1something.
