This is a precious little gear-profiled twisty vase-lamp thing!
11/2/12 - Thanks for the all the likes and pictures of your prints. Happy people are enjoying this design! :)
Print with zero infill, 1-3 perimeters, and a few solid layers. Delete the last few layers of code, stop the print before it starts bridging, or cut off the solid layers after the fact.
*Update: With Slic3r 9.4 you can choose how many top solid layers you want. You want 0.
Insert LED tealight. Ahhhh, pretty.
