BOLTS!!!!
It suddenly came to me, about a minute ago:
I don't want Ts. I *REALLY* don't want to deal with Ts.
And, I agree that friction fit pipe probably will not hold without some
sort of support.
However, we could use BOLTS!
Drill a hole through both walls of the pipe, so that they line up. Do
this at each end, and drill corresponding holes in the flanges of the
connectors. Countersink the holes on both sides, so that the bolts and
nuts don't stick oout past the surface of the plastic.
I would be willing to make some (or all, depending on how many we need)
of these and bring them with me to whatever event we do this at
(assuming I come).
And after writing this post, I realised that this limits you to 2
dimensions. There is a way around this: drill more holes in the ends of
the pipes, offset by 90 degrees (or whatever) from the other holes.
