I've found a number of organizers for angle grinder discs, but none that met my particular requirements. So here's mine.

• 4.5" discs with 7/8" arbor
• Post that holds the discs in place is on the base, not the cover, so you can select a disc in the middle of the stack easily
• Is the right height (coincidentally also 4.5") for the Milwaukee Packout toolbox that holds my angle grinder
• Screw-on base

I printed this using soluble support because the base is mostly empty to reduce weight, but if you don't have that removing the support might be a pain. I'd probably just fill in the base if I were printing it in just PLA. I've included a model for that, but I haven't personally printed that one.

This version of the model does not include my cool logo from the pictures.
