The idea derives from countless failed prints on my Ultimaker the last two year. By pushing the machine to something it cannot do, new interesting things happen.
The shape is generated by cutting it horisontally in layers of 0.2mm's. (which is the same as the layer height i print with). It is then duplicated rotated along its center axis, before moving it 0.2mm upwards. This creates a solid, with 0.2mm "wings" coming out of the shape.
It is suprisingly flexible, as you can see in the pictures.
Printed from Cura.
Single (0.4mm) wall thickness (on a 0.4mm nozzle)
