It is hard to beat GT2. It is the current state of the art in belt-tooth profile. (except for the identical G3)
But if you are using a belt, then just buy a $30 Omron encoder. No need to build one as it would be hard to make a better encoder. I doubt you could make an encoder as small and accurate as the Omron using normal CNC equipment. But if you could fit a pulley to the spindle, why can't you fit an encoder disk?
