About this 3D model
The symmetry of this pattern makes it look nice from two perspectives: when observed from above and from one side. Diameter is 20 mm for the 0.2 and 0.5 mm cage bars. Diameter is 50 mm for the 1 mm bars. The printed version has got a sphere diameter of 38 mm, and bars diameter of 0.9 mm. The supports were created with the B9Creator software and they worked like magic: they detached very easily leaving no visible marks. The print was performed in draft mode: at 100 micron layers.
