CD cake bung (customizable)

I've been using some CD spools from faggahz's design (http://www.thingiverse.com/thing:1136895)
and storing them in CD cake boxes. Once you've cut the central spigot from the lid you get a hole, which I've filled with a simple bung. I've added the option of a text note to help sort the cakes for plastic type.

Edit 01Feb22: Thingiverse haven't fixed customizer. I recommend that you install OpenScad if you want to customize.

Edit 25Jan23: The new Thingiverse staff have fixed customizer
