Size of Vault STL files for world building

I’m currently building a region sourcebook, but I want to develop it to include ‘game compatible’ locations.
I don’t have a 3D printer but I’d like to design locations that players could create for sessions.
I’m pretty competent in Sketchup, and I wanted to make Vaults that conformed to the dimensions of the modiphus STL files.
Can anyone help me with the actual size / scale of the sections so I can make sketches files so I can at least make a visualisations of the locations?

For the Vault pieces they have actually posted the dimensions in the store listing



Although note: the Utility Doorway wall is not 2x wide a normal wall. That screwed up some plans that I had drawn up.
