How to turn a flat surface into a rounded one to avoid overhang issues ?

[wayne67VL6]

I'm trying to make a stand / foot for a bbq. The basic design works well, but uses a lot more plastic than is needed and increases print time. So I've extruded out a section, but it has a flat base (see image highlighted in yellow).

How can I convert this to an arch or angled component so that it falls within feasible range for printing without supports?

Select the long edges each side of the yellow mark and add a 45 degree chamfer.

Thanks - that looks good. I'm going to try with a fillet of 10mm as well which looks like it gives a decent arch.

Fillets are better on the steep side, need supports on the higher flatter portion, top 10% of the fillet, no better than the flat surface you are trying to fix.
