This tiny little thing locks the rotation pins in place for the y-axis upgrade on a Stepcraft D series CNC machine. I had one of the pins coming out (the glue failed) and although there are two pins transferring the rotation from the motor to the shaft, you don't need any of hem falling out.
The print locks into the secondary screw hole for the brass axle mount. This means you'll need an M4 5.75 mm (metric) or 1/8" x 1/4" length (imperial) bolt to fasten it to the axel mount.
