small features turning into blobs - PETG printing

I'm having trouble getting things to print that have small features alone on a vertical section.  For example, the nut holder on the fan shroud - the last several layers or just the nut holder and while the rest of the print looks fine, this section looks like it melted into a bit of a blob.

I also had similar issues with a rabbit model with thin ears sticking up by themselves.

Is there a setting I need to change?  I've already reduced the temperature to 225C and the rest of the print looks fine, not stringing etc.

RE: small features turning into blobs - PETG printing

I think you need more part cooling on the tiny parts.

Cooling settings is under filament tab - to do more advanced settings as fan speed, you need to be in expert mode.
Try changing the settings under Cooling Thresholds.

Have a look at my models on Printables.com 😉
