The design for this LED table lamp is an excellent test for any 3D printer, due to the vertical fins being fairly thin, requiring additional support from a small rectangular cross piece to make them stiffer. Consequently each fin's cross-section assumes the shape of a cross, necessitating twelve right-angle turns in each loop and precise control to avoid moving the fin out of position while extruding the loop's filament. This becomes increasingly challenging as the printer nears the top part of each fin just before they join together. I utilized three colors for this print, resulting from an initial misjudgment of the amount of filament available on the spool for the bottom orange color. Upon realizing it was running low, I switched to a fuller reel of a slightly darker orange, and later decided to top off with yellow after seeing the final effect. Overall, I believe the result is quite pleasing. This lamp is designed to accommodate any one of several LED lights known as "puck" lights, which can be powered by either batteries or wall power. For wall-powered options, refer to this blog page: http://birkbinnard.com/blog/wall-powered-led-lights/. A short video showcases the lamp with a battery-powered LED on a small turntable. The requirement for twelve right-angle corners in each loop of each fin led to an extended print time of 40 and three-quarter hours, achieved at a print speed of 80 mm/sec and a layer height of 0.200 mm.
