What scale should this be printed at to be accurate to the prop?

In looking at the exploded view here, you don't have models in here to fill in the caps/holes in the Phaser 1? Not everyone wants to install electronics...

This model needs to be resized. I downloaded the files as is and loaded them into my slicer. I was a little puzzled when the estimate was only 4.5 hours. Nevertheless, I began the print job and a few hours later when I checked on it, it appears that the model was printing at maybe 1/2 scale.
