I know Festool offers a Sys 1 for RO90 abrasives but its lay flat organization doesn't maximize space and offers about 8 stacks which limits variety. So I decided to stand the abrasives on edge instead and mocked up this organizer for a Sys 2 that gives me 21 slots with removable dividers with space on the sides for extra pads. I'll be trying out this cardboard mockup for a while to see what might need improving but this will help me organize my growing inventory of abrasives and polishing pads for this awesome sander.
