The author remixed this model.
Same concept as the source (FLSun had to, for some reason, remove space from inside the drawer to shape the handle, it had to be fixed), just made it so that the handle is integrated and is not to be assembled
I advise to print it in PETG, as sometimes the drawer compartment gets somewhat hot, but it should work in PLA as well.
Orient it as you wish, but you're gonna need supports one way or another
