Hollow Dome

There is a piece of wargaming terrain I want to build, but is a large hollow cylinder with a lid. The inside supports are using a lot of material and taking a lot of time, so I created this dome to print underneath it to eliminate a lot of material use and time.

This uses some support near the top of the dome, but much less waste than without.

It's small, but I use the default Cura tools to make it the size I need.
