A basic ninja throwing star, based on the ones in Naruto. The edges on the top and bottom are rounded to make the bottom half a bit smother. Needs supports. I recomend printing in a higher than average resolution to make the bottom smoother. You will have to do a bit of sanding on the bottom side to clean off the bits left behind by the supports.Designed in Sketchup 8 with Fredo6's Round Corner Tools plugin (A must have for ALL Sketchup users). The shuriken pictured above was printed on a Makerbot Replicator 2 with a layer hight of 0.2mm, and 3 shell layers. Should have a length and width of about 100mm.
