The Sonostar Hub & Cover Kit does NOT contain the PVC struts that are needed to complete the dome. However, the instructions for measuring, cutting, drilling, and labeling the struts are included in the instruction manual in the Bubble Dome Basic Hub Kit. This kit is for the DIY'er who wants to save money by cutting and drilling their own struts.
The Hub 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.
Sonostar’s Bubble Dome Cover is made of durable .3 mm /650 gsm PVC, ultrasonically welded, and is designed to specifically to fit the frame. It has a zippered front door, two triangular windows that can seal shut, and a canvas skirt that will make a ground level barrier to weather and animals.
