These twin containers should slide into each other smoothly.
You can adjust the following parameters in
customiser:
Render resoltuion: $fn=100;
Object height in mm
rotation in degrees (try 90, 180, 360)
thickness= object wall thicness in mm. My default value is very thin. Almost 1 layer.
First side of ellips in mm: side1
Second side of ellips in mm: side2
Base thickness in mm base (no need to modify this value)
space mm. Empty space between two shapes in mm's, Adjust this value so that two objects smoothly slide into each other without friction, or with minimal friction.Default is 0.8mm. Increase if the friction is too high or objects do not slide at all. Leave as default for your first print.
The following short video shows how they should slide:
