The lamp shade is shaped using Autodesk Maya and a Python script that auto-constrains polygonal platonic-solids to a hemispherical NURBS surface. The top hole has an inside diameter of 3.5cm for a snug fit with the light socket. This was the user's first print with support material, resulting in a 26-hour print time on a Makerbot Replicator. The total energy consumption was 1.63 kWh. A 40-watt halogen bulb was tested but it melted, requiring sanding down of the hole for a new bulb or using a LED bulb in future. The blog post is available at http://www.akeric.com/blog/?p=1868. The shade was printed with natural PLA for transparency and set to 40deg HPB and 210deg extruder temperature, with 5% infill and an extra shell. Support material and rafts were used to handle overhangs.
