You can print the Jaw from his files at the link above.

I added a slot to insert a mini LED tealight, I suggest at least 6 outer wall layers top and sides so that it doesn't shine through the forehead. It will still show through in the dark at that depth, but it's pretty opaque in a lit room.

If I printed it a third time I would probably try 12 just to see if I could make it less see-through in the dark just for fun, but we're not planning on using it in any dark rooms so it shouldn't be a problem as is.

When I printed it the second time, it was a bit loose for some reason. If you have that issue
just add 2 layers of painters tape on two sides and it stays in firmly.

You should be able to slide the tealight in the bottom, and maneuver it into the slot using the eye holes.

This is the one I used. Anything that's same size should work fine.
