Geodesic Dome or Sphere Model

Description

Geodesic Dome or Sphere Model Here are the parts you can use to construct a Geodesic Dome or Sphere model (2V frequency) - easy to print and construct. The result will be a dome/sphere of about 40 cm. in diameter. What you will need For a Dome : 10 four-way hubs 6 five-way hubs 10 six-way hubs 35 A-struts (long) 30 B-struts (shorter) 130 rivets 3.2 mm x 6 mm (or 5 mm) 130 M3 washers rivet gun For a Sphere : 12 five-way hubs 30 six-way hubs 60 A-struts (long) 60 B-struts (shorter) 240 rivets 3.2 mm x 6 mm (or 5mm) 240 M3 washers rivet gun Construction The A- and B-struts differ in length and to avoid making mistakes, the A-struts are marked with a "-" on the back. Make sure to keep the back of the A-struts on the inside of the dome or sphere. You can either have the hubs on the inside or on the outside of the dome/sphere. 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). 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). Enjoy !
