Fins2

The design for this LED table lamp is a good test for any 3D printer. Because the vertical fins are fairly thin I added a small rectangular cross piece to make them stiffer. Consequently each fin's cross-section has the shape of a cross. So for each loop of each fin the printer has to make 12 right-angle turns, and it has to do this without moving the fin out of position while it extrudes the loop's filament. This gets to be quite tricky as the printer nears the top part of each fin just before they join together.

I also used 3 colors to make this print. I mis-judged the amount of filament I had on the spool for the bottom orange color. So when I saw it was running out I switched to a fuller reel of a slightly darker orange. After seeing how this looked I decided to make the top yellow. Overall I think the final effect is quite nice.
