Say you thought you had this wheel for the 25d metal gearmoter motor. And you lost either the wheel or the mounting to the motor. Quick fix... Print normally. So, you push in to the motor, and there's this tad part that gives way, you have push into that which will ensure the motor won't get loose. You can modify this further to deal with the fact that this was modified in mind that you had the track, if you don't modify this.
