Simple design need help Blender to Cura

[Shayster 0]

I am just trying to create a cap. So a cylinder with one face removed at the top. Every time I bring it into Cura it add a fill at the top and some sort of fill in the middle. It's driving me crazy!

In blender you have to model the width of the walls of the cylinder (not in cura).  So your cylinder needs another cylinder inside it to hold the air.  And you need a bottom to your inner volume.  And your cap also needs to have a top, a bottom, and walls.  As a minimum.

Blender kind of sucks at making 3d things.  It is designed to make computer graphics (stills and images) and not to make real things.  But if you are very good at blender I'd stick to it as each cad has some learning curve (although blender's learning curve is insane).
