I wanted a better way to keep all my orbital sanding discs organized, and I couldn’t find a solution that was both modular and stable with minimal hardware. So, I designed this stackable sandpaper storage system!

It’s versatile, modular, and super stable — the top, middle, and bottom holders keep your stacks steady, no matter how many bins you print.

The storage units have integrated dowels that fit into other units, so no extra hardware is needed, except screws to mount them to the wall. I also added a hexagonal floor design to save filament and let dust fall through.

You can print files for all the common grits, “USED” bins, blank bins, or even customize the text. A spacer ring is included if you want some space between stacked units.

It’s easy to print and assemble, and you can make as many as you want, mix and match, and create your perfect workshop setup.

Enjoy organizing your sanding discs!
