Nightlight3
This is probably the most complex part I have designed so far, and it took me 3 tries to print it successfully.
The first print finished OK in about 11 hours, but I had an internal design error that I did not notice from the outside, and the curved surfaces were too thin. So I fixed that and printed again. This time, because of thicker walls, the print needed about 14 hours. But a power failure stopped the printer after about 11 hours. (High winds in Southern California knocked some trees into power lines.) It finally printed OK the third time in just over 14 hours.
Photo1 is the part by itself, right off the printer. The inner surface comes to a point, but of course no printer can print that. So I used a small file to make the point look like photo2. Photo 3 shows some detail of the outer surface - the Atom2 surely does make excellent quality prints. Photo 4 is the light with the LED set to white, and the other photos are with the LED set for different colors.
I used Craftware to slice the part. There were a few very thin strings on the inside of the part. For this print I reduced Prime/Retract from 6 mm to 5 mm, but kept Retract Speed = 150 mm/sec. I also used the LCD panel to change Acceleration from 9000 to 3200. This change did not have a noticeable effect. I'll probably go back to Prime/Retract = 6 mm and just get used to a few thin strings on parts like this.
I'll post the STL file later today; I'm going to try to find a way to get better photos with the LED showing different colors.
