This lightweight (about 15 g) but strong bracket is made from 3mm-thick black anodized aluminum and is specifically designed to work with the typical faceplate mounting holes of NEMA 17 stepper motors. The slots through which the motor mounts to the bracket allow for 2 mm of play for fine-tuning position, and four 6 mm M3 screws are included for securing the motor to the bracket (note: these M3 screws work with all of the NEMA 17 stepper motors Pololu carry; different screws might be required when using this bracket with stepper motors from other suppliers). The other side of the bracket includes a variety of slots and holes that can be used with #6, #8 and M4 screws.
This bracket makes it easy to mount and integrate NEMA 17 size motors like Pololu's stepper motor with lead screw into your project. These brackets also fit the 42×18.6mm Sanyo pancake motor and the 42×11.6mm Sanyo pancake motor, though the two Sanyo motors have short output shafts that will only extend two millimeters past the edge of the bracket.
