I liked the asymmetric look of my previous boomerang, so I decided to pursue the idea a little further.
This one has a kind of melted cheese, Maniac Mansion, Calvin & Hobbes-ish look to it which I quite like. I made sure to center the hole around the center of gravity for easy one-finger catches.
Made in Onshape. Have a look at the part studio to see how it was constructed and to play with the shape if you like.
