3D-printed would be fine, except those are just statues. Aside from mounting points and IO holes for the Pi, models for an actual enclosure would need to be subtly adjusted so the holes for the keyboard and screen match up with available off the shelf components to add in.

There are quite a few options that already accommodate a pi, if you don't want to customize... see my other comment upthread for a couple, but that's just the ones I happened to have bookmarked, there are a _lot_ of results if you just search for pi cases on thingiverse or something.
