Tubes1

The concept for this lamp occurred to me when I saw a photo of a large geode. That reminded me of the Devil's Postpile national monument, which, like the geode, has a number of hexagonal structures arranged in a somewhat random manner.

The basic shape of this lamp is the top of a sphere, to which I added a number of randomly place hollow light pipes. The pipes are hollow to let the light in and out their tops, and they have 7 sides because this type of structure would never occur in nature.

This lamp printed in a little more than 31 hours using a print speed of 90 mm/sec and a layer height of 0.200 mm. I used no internal supports, but to help with printing the top area of the sphere I did specify variable layer heights. For people who do not wish to print something this size I will be posting Tubes2 soon; it is about half the size of Tubes1.

This lamp will accommodate any one of se
