Customizable Kitchen Light Bulb Globe for LED light bulbs
by contour, published
This is a spherical light bulb enclosure that has a flanged base. I designed it to fit into the light fixture in my kitchen. Normally, kitchen light bulb globes are completely sealed, and have no ventilation. LED bulbs, however, are very sensitive to heat buildup, and must be adequately ventilated -- they cannot be totally enclosed. To solve that problem, the light bulb globe I designed has a circular hole in the bottom and six rectangular holes around the top, to allow air to circulate through the globe.
The diameter of the sphere, the diameter, height and angle of the flange, the thickness of the globe, and the number and size of the holes can all be customized.
I printed it with natural color ABS filament on Kapton tape covered borosilicate glass rubbed with ABS juice, with the extruder temperature set tp 225 degrees C, and the temperature of the bed set to 110 degrees C. I allowed the finished print to cool to 21 degrees C. There were no issues with the print sticking to the treated glass, or with it unsticking when the print was done. Used infill of 0.4.
