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
