Experiment

thingiverse

Another experiment. This one uses Grasshopper, a parametric modeling add-on for Rhino to create a unique surface. I haven't gotten around to casting this yet, just the thin walled 3d print. Instructions If you can get it done, print with 0 infill and 2 ply walls. Might be worth adding some ribs to it at a later date to make sure it doesn't deform.
