Spirals 4 and 5

cults3d

I printed two identical-looking LED lamps using the same transparent yellow PLA filament, but they differ in design. One of them, spirals4.stl, has diamond-shaped patterns that don't quite reach the top of the lamp due to a slight gap between the inner and outer surfaces. I intentionally designed it this way because I thought the diamonds would be more visible if they didn't directly reflect light from the bottom LED. However, after testing spirals4, it became clear that my assumption was incorrect. Therefore, I modified the design to make the inner surface coincide with the diamond patterns, and extended them to the top of the lamp. The result is spiral5.stl. Since all my designs are 100% parametric, making these changes was a breeze. For more information on this topic, please refer to my blog post at http://birkbinnard.com/blog/parametric-modeling/. Comparing both lamps, spirals5 printed significantly faster than spirals4 - in just over 31 hours as opposed to the 44 hours required for spirals4. Both designs use the same settings: a layer height of 0.200 mm and a print speed of 200 mm/sec. The LED lamps can accommodate either battery-operated or wall-powered "puck" lights.
