I liked the original but couldn't print them because they were the max of my build space and overhangs because I didn't use support. So I created these trays they are 80x80mm and have beveled edges so you don't need to use support.

Print and stack then gently shake.

Now that I think about it you can probably skip printing the Quarter tray because there's really no point for that one.

I designed these on tinkercad.

The more I look at them the more I think I might make them in circular cups that fit together.

I guess that's why I marked these as "This thing is a Work in Progress".
