Christmas tree - Gravitrax compatible part

This Gravitrax custom tile features a helix slide which resembles a Christmas tree. The ring, which is printed separately, has to be glued to the main part. Small warning: in my case, the ball was getting stuck near the exit, so I had to use a file to clean up the piece. This is not caused by an issue with the design, but rather the fact that I didn't want to add more supports.
