2 inch sanding disc organizer

Bought the 2 inch/50mm sanding disc pack with 12 different grits on Amazon and needed an organizer. I found some but I like to use as minimum material as possible so none of them were to my liking. Made a simple one that is still strong enough out of PLA. The fit of the discs is a little snug so they don't fall out easily. I used .3 for layer height but use any.
