Two kinds of asymmetric tribladers. The green one is in the files called "wonky three", the purple one is even more squiggly and is called "wonky three 2". There are also "blunt" versions, which have an airfoil with a little more drag since the other ones had a little too much spin at first for my liking.

As always, print with lots of solid top and bottom layers and perimeters (4-5 will do) and about 25% infill.

I got this model on thingiverse from lapjoint
