Hubs for geodesic tent 2V (PVC or polypropylene frame)

Hubs for geodesic dome of 20 mm diameter polypropylene or PVC pipes.

Redesigned the idea of hubs for my needs. The estimated diameter of the dome is 5 m. Due to the weight of pipes, they are not held in the fixtures, so I had to make frames for them. Locks prevents the frame from flattening under its weight.

2 types of hubs (see Geodesic dome calculator: http://acidome.ru/lab/calc/#1/2_Piped_D100_2V_R2.5_beams_20x20):

- 5-terminal (orange)
- 6-terminal (green) - the location of type B
