The Catenoid Bead was created in Blender from a cylinder mest. Then loops were added along the length. Next, the loops were scaled to create a catenoid minimal surface. Finally, a 1.18-cm radius cylinder was used with a Boolean difference modifier 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.
