"Floating" tiles collection - Gravitrax compatible

This Gravitrax custom tile has 4 small curves and 1 straight line. The ring, which is printed separately, has to be glued to the main part. It can be used as a standalone piece or connected with others using the included connector parts. When combining at least 3 pieces from the same collection, the middle one no longer requires spacers, giving the effect that it's floating. Look at my profile to find similar pieces that can be combined with this one.
