Klein Bottle

cults3d

Surface discovered by Felix Klein (1882). Is an open non-adjustable math surface whose Euler characteristic is equal to 0 (it has no interior or exterior). It can only be printed in 3D after adding some inner thickness. It was just a practice inside my experimental drawer, to model an non-directional surface using basic rhinoceros 6.0 tools, without programming. *Free model for educational applications
