Two of the brackets on one of my existing bags and one on the other are starting to give out, so these will serve as a replacement. These new brackets also allow the bags to be stacked one on top of the other.  So far, they have only been stacked for a day or two, but my (very full, very heavy) bags have been holding up nicely. These new brackets seem to be much more sturdy than the originals. I printed my prototypes from an apparently discontinued ABS+PLA mix because I have a ton of the stuff, but I recommend using at least some type of ABS because PLA on its own would almost certainly warp under the weight if it didn't buckle outright.  

I also suggest using a lot of walls and infill for strength.  With a .8 mm nozzle, I used 4 perimeters and 50% adaptive cubic infill.

For those who downloaded the original, this version has been tested and resized to fit the stock pipes.  To stack two bags, one needs eight corners, four stackers, and the original pipes (less the four bottom pipes from one of the bags).
