Interlocking ramekin dish stacking system

Base, lid and intermediate rings to stack 92mm OD 83mm ID glass dishes that come with desserts in the UK. Might be similar elsewhere. Printing the base, lid and a pair of rings is enough to stack 3 dishes as shown.

There's a bit of play on each so possibly could go slightly over/under the dimensions designed for.

Each print will need support and careful cutting. Might be easier to break them up and print directly on the bed. Haven't printed any more than the first/only set.
