PVC Tetrahedron

I’ve searched for polyhedrons made out of PVC pipe and only found a few pages that used odd fittings, but I found a way to make a tetrahedron with common fittings.

I made this basic tetrahedron with:

  1. Put the street elbows at each end of the  pieces of pipe.
  2. Put the male part of the street elbows into the side outlet elbows so the other two openings of the side outlet elbow are pointed away at 45 degree angles.

You can also use regular elbows or tees instead of street elbows.  You will need a short piece of pipe to connect to the side outlet elbows (I used 1.5 inch lengths since the sockets are about 0.75 inches deep each.)
