Pillars filling insufficient

[Erik84750 0]

In the attached project file below there are two bodies. In the left body there are four pillars (diameter 8mm) with a 4,2 mm diameter hole (15mm deep).

They are situated in the corners of the larger rectangular shape.

 

After printing I notice that these pillars are brittle and not fully filled.

 

How can Cura be made to fully fill these pillars (except for the hole of course)?

Try reducing infill line distance

Thanks. I notice my filling density is 20%. The infill line distance was invisible untill I changed the profile setting and made it visible. When I change the filling density from 20% to 60% the filling line distance reduces from 6mm to 2.0mm.

Is that acceptable?

You should be able to stick with 20% and reduce the distance independently to 2mm
