This is a mini Santa Claus that sits on the end of you bassoon bell, if you don't have a dual extruder you might want to paint it so it looks like Santa. If it does not fit in your bell then get a lighter and warp it and squeeze it so it gets skinner. There is still a hole in the top for air to get out.
