Solid Shell within Infill? Cura 4.0

[3DSmokeware 0]

I have a prototype for a client that keeps failing.

On an angled cylinder extruding 80 degrees from a flat plane, the joint between its shell and infill at the base has very weak fusion. This is happening with Matterhackers Build series PLA at a .2 Layer height and a grid infill of 20%.

So in my efforts to remedy this problem, I am wondering if there is a way to print the base of the cylinder that's vanished through the slicing process and been turned into the void space that is infill, as a shell within the infill. I aim to increase the stability of this part of the print by basically trying to set it inside like a post in the ground.

Is this possible in Cura? Or is it something I have to do in the export of my model from my CAD software?

 

Any suggestions for this or more obvious solutions to this problem would be most appreciated!
