Help on overhangs

[oneredlime]

oh i did put supports beneath them but i think i didnt do the settings correctly.
i drew the model myself for now the length of it is like 10cm/4 inch?that is possible but im just looking for a way to do this as i also have problems printing fillets from the bottom up. feels like there should be some setting where i could do to make it support better and able to print nicely except that i don't know where it is.

edit: i drew the thing in like 20mm...so i scale it up to slice
