Replacement for the X and Y axis pulleys (which were bad in my kit). Its suitable for the T5 belts, it has 10 teeth and a hole diameter from 5mm. Added two holes for tapping M3 threads for the set screws.
Works well as long I wait for replacement.
Use a 5mm reamer (5H7) to fit the axis hole. Use a M3 thread cutter to cut the threads for the set screws.
