2 sizes of organization trays, originally meant to be used for jewelry, but it can be used for much more.
The big one is about 91mm in diameter and 30mm high.
The smaller one is about 71mm in diameter and 23mm high.
They have their own build plate so that you can print the one you like.

I've added extra bottom shell layers to prevent the core from shrinking, and then minimized the seam gap.
