3V 3/8 Mega Dome Kits

Our 3V 3/8 Geodesic Dome Kits are designed for use with 1" or 1.5" Schedule 40 PVC tubing. Our Basic Hub Kit is great because it allows for the most flexibility. The kit only includes the hubs, nuts and bolts, and a mallet and you are free to cut your PVC struts as little or as big as you would like your dome to be.

This 3V 3/8 PVC Geodesic Dome Shelter is just less than half of a sphere. If a sphere is 8/8, and a hemisphere is 4/8, then you can see that the 3/8 configuration is just less than half.

If you are looking to make geodesic dome building even easier we can cut and color code your PVC struts for you. Just click the "Hub + Strut Kit" option, choose your size, and add to cart. If you do not see the size you are looking for click the "Custom Kits" button and submit an inquiry.

Custom Kits


      Choose whether you would like to order just the Basic Hub Kit and cut the struts yourself, or order the Basic Hub Kit together with a set of precut, predrilled, color-coded struts (Hub + Strut Kit).

      To complete a Hub + Strut Kit order simply choose from several options based on the diameter of the finished dome.
