I am using Blender to model my stuff, but i have not yet learned how to make parts solid in some areas of the model.
For example: i make a box in two parts that are supposed to be screwed together. As i do now i use boolean operations to make small "predrilled" holes in the box.
But when slicing they only get as thick walls as i have perimeters. And then my box get very weak were the screw screw into.
I hope you undertstand what i mean. I want to make 10mm thick pillars (with predrilled hole) inside the object that i can screw into.
I don't want to use 100% infill.
Probably easy, but i have yet not figured it out.
