The Cube Bead was created in Blender by adding a cube mesh. Then a bevel modifier was added. Finally, a Boolean difference modifier was used with a 1.18-cm cylinder to create a hole for the wooden dowel.
 
The CAD package includes the bead files for the Accent Table and the Candlesticks. CAD files include the Blend, STL, and gcode files. Please double check the scale and units before printing.
