It's a Wonderful World organizer cups

Cups with screw on lids for the It's a Wonderful World board game. Designed to be placed directly onto the board.

There's probably better inserts out there but:

1. Getting tolerances for lids on the one I tried was being annoying so I went with customizing a screw on model instead.
2. Given it's my first organizer and first time using OpenSCAD I'm reasonably happy with it.
