Eachine Racer 250 Arm

This is a "heavy duty" replacement arm for the Eachine Racer 250. For molded ABS the factory design works well but is very weak when printed. I designed this beefed up arm to be easily printed while remaining strong and lightweight. Cura shows this arm weighing only 2 grams more than the printable factory replacement. This weight is saved by doing away with the threaded inserts and carbon fiber spacers required on the original arms.

Uses either factory screws or #6 x 3/8" directly into the plastic without spacers.
