aquamaxx skimmer solid O-ring

Designed this to replace the rubber height O-ring for my Aquamaxx HOB skimmer as i noticed the rubber one would slip and was unreliable. I used it on my HOB 1.5 model but it will also work for the HOB 1, WS-1 and HF-M Skimmers as they all use the same size collection cup. Uses a 5/16 x 1.5 inches long bolt and nut combo to tighten it around the skimmer cup. used PLA but probably could use PETG as well. 210C at the nozzle and 60C at the bed.
