This is a spinal column tea light holder. My wife asked me for a candle similar to one seen in the fourth Harry Potter movie, so I modified a free skeleton model into this candle holder. I have sliced it to fit on my Thing-O-Matic platform and print without raft or support. I then glued it together with acetone. Print and glue together. This is designed to hold a standard 1.5 inch diameter tea light.
