Marble Rush compatible spiral start

Hi Everyone, happy to finally contribute to the community. This is a model I've designed and printed with my son for his Marble Rush set. We've printed it on A1 Mini and it fits the set perfectly. If you plan to create your own profile I would recommend a manual paint support just in the place where ball ends, everything else should print without supports. Enjoy!
