If you use a small gap (i.e. 0.1mm) you will find that the brim does still mostly touch the model but is easier to remove.

Surprisingly, it does still help reduce the model's corners curling even when there is a visible gap between the inside of the prim and the model perimeter. This is the model that inspired the brim gap feature.

Printed using PLA, I noticed that the corners on the side tended to lift from the build plate unless I used a brim but the brim was hard to remove without looking ugly so I tried using a wide skirt with a very small gap and it still helped reduce the curling of the corners. I am guessing that a brim helps reduce curling by reducing the temperature change between the layers at the edge of the model.

I have also noticed when printing PETG that corner warping is greatly reduced when the bed temp is increased so for that material using a high bed temp (at least 75 deg) and a brim with gap gives me little warping at the corners.

Try setting the brim gap to 0.1 or thereabouts.

Thanks Iāll try that. Would it still adhere the model to the bed if there is a full gap?Ā
