This support bracket is for the Hayward Skimmer that attaches to above ground pools. It is designed for the wide mouth kit, but can easily be cut to a short length if using the small mouth version. It is designed to print all 3 pieces the coupler will go in the middle between the 2 pieces. Once you have the proper length cut, use a little super glue inside the coupler and slide the 2 pieces together. I also added on some Rubber weather stripping on both ends to hold them in place once installed, as well as to put a protective barrier between the pool liner and the bracket

If printing and using it as is, id suggest PETG or equivalent material that won't warp, printed at 50-75% infill.

If you are going to cut it and adjust the length, print it at 100% infill same PETG or equivalent material.
