Made this for a friend whose skimmer was cracked and falling apart and patched up multiple times. There were none of that same model available online. Took all the measurements from the original. I used 15 - 5mm x 12mm pan head machine screws with washers and lock nuts. I also put bathroom caulking between the two main parts for sealing. I printed it with PLA, but ABA should be used for longevity.
