These are the 6 poles and 6 arch pieces for Sarah's Music Box. They are designed to fit on top of a 4 mm wide rod. The poles and arch pieces must be cut away from the rest of the print flashing with a sharp exacto knife. You only need to order one of these pieces to receive all 6 poles and arch pieces needed to complete one music box.
An overview of how to construct the music box can be found on my
blog.
