Help making smaller details solid

[philask]

Hi, hope you can help!

I've got a custom enclosure for a project I'm working on, it has two pegs which go through a PCB, these are sliced solidly but the part below them is infilled, this causes shearing breaks at the base of the pegs. What I'd like to do (other than the obvious; 100% infill) is to specify "solid fill anything smaller than 4 mm" (or along those lines). Anyone any ideas?

Here's the "finished" preview (two pegs are top right):

And here's the "hollow" (infilled) peg support (which I'd like to be solid):

I think the easiest way is just to add 3-4 more outline perimeters

The way you design the posts may a BIG difference. What program did you use to design it? I had a similar issue as to where a part kept breaking right where the infill stopped and the solid layers started. I ended up using Meshmixer in one instance. And, Simplify3d's ability to add things to eachother in another instance.

It would be a nice function to add to the infill section. More shells works, as more infill too, but you always ruin your first print and heal it with superglue on the small parts.
