Bead Sorter, customizable through SolidWorks global variables.

Print one Lid, one (or two) Bottoms, and as many layers as you need.

Customizable variables:

• Bead Size
• Tolerance
• Wall Thickness
• Base Width
• Height

Hole Size is "Bead Size" - "Tolerance". "Wall Thickness" and "Base Width" should be consistent between layers.

If you don't feel like customizing this file or don't own SolidWorks, you can use the models provided instead.
