This post serves as a historical reference, as improved boomerang designs have been developed. View them by exploring other items. A tri-blade boomerang is featured here, with throwing instructions available online at sites like rediboom.com. The model was printed in ABS, within a 20x20 cm bounding box and 3.5 mm thick; slightly larger dimensions are acceptable, but the printing area restricts size.
