15-105mm hollow hemispheres w/ ~2.5mm thick walls

My hollow spheres are popular so I decided to work on other shapes as well.  Basically made hemispheres in tinkercad going up in 5 mm increments then cut a hole inside with a hemisphere that was 5 mm smaller and centered inside.  The size of the model indicates the dimensions of the base. Example the 40mm hemisphere has a 40mm diameter base. Height will be half of the base diameter.
