Gravitrax Roundabout

My 7 years-old son invented this design of roundabout to have a nice spinning effect when the marbles are rolling through it. You can print the wheel in any color (the pink one is for my daughter).
I had to put a slope between the entry and the exit point to avoid that the marbles remain stuck - follow the arrow.
Supports only required to print the wheel. Depending on your printer resolution, small rework (sanding) of the rotation axis required to ensure a nice spinning.
Clip design taken over from ffleurey´s Marble lift.
