Tried printing the frog from this set at 75% scale, and it came out like this. The original 3mf for this one doesn't include supports. What should I adjust on my printer to get better overhangs without supports?

On my printer I added an external 15cm pipe fan that blasts at the print. I only turn it on on prints that need it, but then cooling and overhangs are perfect.

    I've heard some reports that printing outer walls first has a positive effect on overhangs. I have it on in my slicer and it doesn't seem to negatively effect anything.

    Temperature, speed, flow rate, cooling.

    In other words, close to anything. Follow a calibration guide. Also keep in mind that some filaments just don't make good overhangs.

    Very few printers are going to be able to do 90 degree overhangs even close to nicely. Bridging? Sure. With significant overhangs, it’s always going to wiggle a bit until you get some more layers.

    If OP weren’t using this to get as close as possible, I’d say the answer was organic supports coming in from the bed.
