If you use Blender Brushes for papercrafting, you probably have a number of them in different sizes. We have Simon Says Stamp brushes, which all have the same size handle. This Gridfinity block holds the brushes in easy reach, with the heads separated so they don't touch.

We've included three different STL files. All three are 2x2 Gridfinity units, but with different numbers of pockets:

• 3x3 rectangular layout. Wide enough spacing for the largest brush sizes.
• 4x4 rectangular layout. The densest layout, but really only suitable for the small and medium brushes.
• 5 pocket in a circular layout. Keeps the heads facing away from each other around the circle.

We've also included the Fusion 360 file if you want to adjust anything. The pocket sizes and spacings are parameterized.
