Gravitrax Junior Raiser/Elevation Stone (Erhöhung)
For a thight fit at the top use 100%, for a biased fit top/bottom use 100,5% X/Y (Z 100%) and a thight fit at the bottom use 101% X/Y (Z 100%).
The uploaded profiles are in the biased version(100,5%).
I prefer to print without support, depending on the material the inside overhanging corners can have minor optical defects, please check the photos.
