This module uses the same strategy as used in Amafirlian alternatives to end up with something that looks like a distorted tetrahedron.

Building Instructions[]

  1. Take two rods and connect them at a 90° angle.
    • Make sure the polarity of the two rod ends that are closest together are opposite polarities.
  2. Connect the next rod in the same way to the second rod, but also perpendicular to the first rod.
  3. Connect the fourth rod (again in the same way) to the third rod, but also parallel to the first rod.
  4. Connect the fifth rod (again in the same way) to the fourth rod, but also parallel to the second rod.
    • At this point the first and the fith rod tend to get stuck to one another. To avoid this connect it parallel to the third rod instead of the second. Then when connecting the last rod, turn the fourth rod so the fith is parallel to the second.
  5. Connect the sixth rod (again in the same way) to the fourth rod, but also parallel to the third rod, so the first rod is also connected to it in the same way, closing the cycle.


Properties[]

  • The size can be varied slightly by changing the location where the rods connect, (as shown in the figure).
    • If you make a larger version you need to change the orientation of the rods, again keeping the two rod ends that are closest together opposite polarities.
