I'll bet there are many ways, but what I do is drill 1/4" holes below
each notch where the tubing will lay. Then use small zip ties through
the hole and over the tubing. Very secure and easy to do if you stack
all the supports together first and then drill the holes using a drill
press. It takes a lot of ties, but small ones are pretty cheap for a bag
of 100 ties.
