Rhombi Sphere

You may subtract a part of the sphere with negative volume in Slicer and sit it on any lightbulb as a lampshade. For impressive shadow projection make sure your light is as small as possible. Avoid diffuse bulbs, better go for pointlight style LEDs. Many years ago I got very inspired with geodesic structures thanks to the work of TaffGoch who shared his comprehensive work in the SketchUp community. check him out for more: https://3dwarehouse.sketchup.com/user/0058532540730737055623450/TaffGoch btw: SketchUp is still free as an online tool and makes it very easy to produce STL files. For me still the most powerful 3D CAD software with a very low learning curve and a fantastic community.
