<h3>Geodesic Dome or Sphere Model</h3> Here are the parts you can use to construct a Geodesic Dome or Sphere model (2V frequency) - easy to print and construct.<br> The result will be a dome/sphere of about 40 cm. in diameter. <p> <b>What you will need</b> <p> <b>For a Dome : </b><br> <ul> <li>10 four-way hubs <li>6 five-way hubs <li>10 six-way hubs <li>35 A-struts (long) <li>30 B-struts (shorter) <li>130 rivets 3.2 mm x 6 mm (or 5 mm) <li>130 M3 washers <li>rivet gun </ul> <p> <b>For a Sphere : </b><br> <ul> <li>12 five-way hubs <li>30 six-way hubs <li>60 A-struts (long) <li>60 B-struts (shorter) <li>240 rivets 3.2 mm x 6 mm (or 5mm) <li>240 M3 washers <li>rivet gun </ul> <p> <b>Construction</b> <p> The A- and B-struts differ in length and to avoid making mistakes, the A-struts are marked with a "-" on the back.<br> Make sure to keep the back of the A-struts on the inside of the dome or sphere.<br> You can either have the hubs on the inside or on the outside of the dome/sphere.<br> If you feel confident about constructing the dome/sphere without making mistakes, you can opt for the A-struts -without- the "-" mark (A-strut-v2).<br> Another way to avoid mistakes is to start with the 5-way hubs and all of the B-struts and construct five-legged "stars" (see pictures).<br> <p> Enjoy !
