I'm also sure it's an 3D print and based on a altered existing design. But the Pyra case is also based on the Pandora design and the greek company needed many months to alter everything into the current Pyra case, making the actual molds not even counting.
No, it isn't. The Pyra case was a complete recreation, we didn't have any of the original design files for that.
It's been designed from scratch, based on Pandoras design.
GPD HAS the original GPD XD design files. Changing measurements or moving some things around (like the cutout for the DPad, the nubs, etc.) can be done within minutes if you have the proper design files.
My wife does CAD, so I know how that works.
You've got some reference points and the CAD software changes everything else itself. You want to make it 2cm wider? Just change the parameter and the CAD software will adopt everything else that relies on that.
So they didn't really have that much work to create the design.

We had 3D prints of the Pyra case many months ago now. Mind you this doesn't look to me like the same sort of 3D printer output - I'm not sure what other types or rapid prototyping there are, of if it was just printed using a different material making it look different to most other 3d printed things I've seen.
It looks like the rapid prototyping they usually do for industrial testing.
We had some Pyra cases like that as well. They are more accurate but easily break, so they weren't usable for me.
EDIT:
Here is a picture of them.
They often are white, but you can also use colors.
They look like those, especially if you look at the keyboard.
