I’ve experience with 2 printers: Ender 3 orig and the prusa mini. Of those 2 the prusa wins. It wins on every front but certainly space/portability.

If you find a box that fits it, pad it a bit. I can see this totally working if handled with care. You can lift the thing with one hand steadily with the z motor. Spools with the holder are going in another box. 👌

Don’t buy an Ender 3 or something of the same category. These are only good to thinker with and brute force learn stuff. They absolutely do not travel well and take a lot, A LOT of space/money/time/frustration compared to the mini.
