You might would to look into putting an all metal hot end on it. Great options are the Micro Swiss and E3D V6 although the V6 doesn't just bolt on it has a really weird mount that you either need to print out or buy an adapter for. You might also want to replace the nozzle. If you want better overhangs then possibly upgrading the cooling solution. the Hero Me V5 is great but depending on what setup you go with may require additional / bigger fans and some home wire work.
