Basic materials for the binaural recording head:
Silicon Ear Models: $24.21 (new on Amazon)
It took awhile to find some the right size and with a base I could work with. These are a good likeness of a real human ear with a nice canal and are the about the same size (65mm) as the ones BinauralEnthusiast.com sells for $99 to $139.

Darth Maul Model Mod:
Eyeballs Halloween Horror Props: $10.99
I’m just using the center part of the yellow eyes. With a little extra red around the edges from a marker and they’re a good likeness for Maul’s. I’m going to use red thread splayed out and embedded in a gloss topcoat for the veins in his eyes.
Dental Acrylic Resin Denture Tooth Kit: $6.99
I used the foam insert from the package the ears came in to make channels for the ears inside the head:
I cut the ear holes in the silicon ears with the sharpened eraser end of a pencil, trimmed away the supports on the mics and mounted the eraser (cut in half) to the backs of the mics, then wrapped with a small bit of shrink-tubing. This makes a nice grip and also helps positions to position and hold them in the ear canal properly. I made channels on the back of the ears for the cords by using a woodburner.
