Drive gear with screw holes for Mini 3-Axis CNC

MakerBlock's "Mini 3-Axis CNC" is a fun project (thing:200895), but I find the servo motor easily slips the drive gear.So, I put the drill holes to screw with to the serve horn. The center hole diameter is also updated. The servo motor, SG-92R come with several servo horns. Use the biggest one.
