NEMA 17 Flexure Damper Mount
A vibration-isolating NEMA 17 motor mount: the motor bolts to a floating 46 mm plate (31 mm square M3 pattern, 22.5 mm pilot-boss bore) that is joined to a 76 x 76 mm outer frame only by four Z-shaped flexure beams, so motor buzz never reaches the chassis or the gyro. The frame bolts down with four M3 screws on a 68 mm cross pattern; print it as shown (flat, no supports) and flip it in use so the motor plate floats 6 mm clear of the chassis, leaving room for the motor screw heads.
