The photo is of a 25% scale print. I have also done 50%, 35% and 18%. The big ones are easier to do and come out more scale looking. I added a couple photos of the real ones I used as a reference. I used my peltor radio hearing protectors for most measurements and guessed at the ones for the mike and boom.
If you search "Gary" on thingiverse you will find the pilot.
