300 Degree downhill tile remix

This is a simple remix of andy40's 10mm tile located on Thingiverse.

I've created a mirror image tile so I coud be build symmetric tracks. To the tell the tiles apart easily I've embedded direction arrows to indicate on which side the marble exits. I really like clustering them so that the marble does a 360 degree turn through a 3 leaf clover arrangement, as shown in the Youtube video below.
