Boomerang Thing 1

thingiverse

This boomerang features three blades and two hubs. To assemble, place the flat sides of the blades down according to the assembly image, then glue one hub piece to the top center. Once dried, attach the second hub to the bottom side's center. The MakerBot successfully printed the 11.5 cm tall blade. For optimal flight, use a spinning motion with the round edge moving in the direction of throw. To lighten the weight, print only one outer layer using "Extra Shells on Sparse Layer (layers): 0" in skeinforge. Be cautious when throwing; this boomerang is made of brittle plastic and may break if used on hard surfaces. Only throw on grass.
