Telescope eye piece organizer tray

Simple tray to hold telescope eye pieces. This tray will accept a mix of 2 inch and 1.25 inch pieces as it is.

Although this is not a customizer, it's fairly easy to adapt the script to create different dimensions and mixes of sizes. Near the top, the included openscad script has a declaration of the following format:

grid = [
[big, big, big],
[small, small, small, small],
[small, small, big]
];
