3mm ZMR 250 Replacement Arm

Print with a high tensile strength material such as ABS, PETG or similar at 100% infill. The spine belongs on the bottom of the arm to help reduce flex in the arm while at full thrust. This was designed using a broken arm from an Eachine Falcon 250 and fits fine on that frame. I cannot promise that it will fit all other generic ZMR 250 frames, although it should.
