Parametric generated lampshade, designed by bonooobong (me). This one is the second version with smaller openings (driven by an attractor)
3D modeled with Grasshopper, printed on my MakerBot Replicator2 desktop 3D printer with Medium resolution (0.27 mm), with the default Medium settings. Should work on any FDM printer with PLA/ABS filament. To avoid bending over, I suggest to 3D print it with Raft.
