Product Description
Inverted gyroid, bone style. Diameter is about 10 cm. This has a pin broken (see lower right pin at "4 pm") to be an "open" hollow object - same size, quarter of the price - wall thickness is 0.7+ mm by design - thus WSF only.
Due to the inversion I have removed the inner structure up to a certain radius (see 3D preview) because without removal all of the 3 dimensional infinity would get stuffed inside - that doesn't work :-)
