This kit does not contain the struts or the cover.
The Standard Bubble DomeHub Kit contains all the 4-star, 5-star, and 6-star hub connectors needed to build a 3V 5/9 geodesic dome. All the hubs have 10 degrees of curvature built into each arm as well as molded holes to fit the bolts. Stainless steel nuts and bolts are included to connect the struts to the hubs. Inside the box, you’ll also find a soft rubber mallet to help you nudge any tight fitting connections together. A laminated assembly map and an instruction book make up the remainder of the kit. Hubs can be either black or white.
