$1dollar ice cube tray dragons teeth....
I used quickcreat and after it was hard I taped around it with duct tape and added another inch....does it look like the real thing.....maybe if you squent a little. I am going to get another tray and chop the bottoms out of it and put the 2 trays togatherand see if I can form it so they look closer to real thing...then I can make them 12 at a time.....</p>
