For wall decoration. On Ender 3 the printing with 1 layer height took around 15 minutes using the full bed size.

I made this art years ago, I just made a vector of it.

The print is not limited by the bed size, if you wish to print a larger one you can separate the model into small pieces.

I made a vector of an already made artwork (https://www.instagram.com/p/Bl_zcZaHXnB/), in this case I use Inkscape.
