Geodesic Dome or Sphere Model

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 !
