Spinning Light Filter 3D print model
Designed to create a spinning light display around room walls, this unit sits above most any incandescent lamp by way of a vertical center rod (supplied by user) that is fastened atop a lamp shade support. The light filter rotates as the rising heat from the light bulb passes up through its fan blades. Lamp light shining up through the many holes in the unit is scattered into a spinning array of light shapes that dance across surrounding walls. Color can be added to the light if transparent color film is added around the interior circumference. Tabs inside the circumference of the cylinder are designed to hold a 2" x 14.63" long ribbon of transparent color film, or lenses, for a variety of effects. The model is designed to fit within a 5.5" cube of space to accommodate small 3-D printers. Of course, a printed model must be suspended at a sufficient distance from the bulb so that heat does not deform the thermo-plastic; user will have to experiment for the optimum distance with the bulb wattage used. A light gage coat hanger wire with a sharpened tip is suggested for the central support rod.
