Problem Slicing Pillars

[mg180 0]

I'm wondering if anyone can help me with an issue I'm having slicing models with thin pillars/towers.

 

Below is an example where I have a model that has four small pillars (to support a RPi camera).

 

When I switch to layer view is shows the lower pillar with no infill inside (infill is only at 20%). 

 

One layer up then shows it try to print the upper thinner pillar completely inside the empty circular space of the lower pillar.

 

As you can see there is nothing underneath to print over the top of and bond to. This means that either the print fails, or the thin pillar will fall off as soon as I do so much as breathe on it.

 

The only way I can see of fixing this would be to increase infill to 99% to guarantee there is some infill for it to bond to, but this is obviously impractical.

 

Is there something I'm missing here? Any help is greatly appreciated.

hello @mg180, please save the project file (File -> Save) and attach the .3mf file to this thread so we can check the model and settings. Thanks.

Thanks for the file. You just need to reduce the skin removal width setting and that will let the small amount of skin that goes inside those pillars to be printed.

That's perfect.

 

Thanks for your help!
