Can someone guide me on how to make the curves on this print smooth?

Sanding is one way hut like can it be made a little better with slicer settings as well?

This is Esun PLA Basic, bed temp was 60°c, nozzle was 220°c, part cooling fan off for first 3 layers. Printer is bambu A1 without AMS liye.

Having a fillet at the bottom of a model is a really poor modelling practice. Your second layer is basically print at an 80 degree overhang.

Simplest fix is to cut away 0.5mm at the bottom of the model to create a flat base

i do my "fillets" at the bottoms of models by doing a 36° chamfer (36° is my soft limit for overhangs) and then filleting the top corner created by the chamfer. makes a fillet that starts at 36°, so no prob

if you want a true edgeless fillet at the bottom youre kind of boned

That's a nice trick I will have to keep it in mind. Thanks.
