Polaris Pool Cleaner Port Killer 2" Plug

I'm renting a house with a pool that was plumbed for a Polaris pool cleaner.  The pool cleaner is long gone but the port just spills water when the filter pump is running.  Thought I'd just it off the easy way since they didn't install a cutout valve.  Anyways, hope this helps.  I thought all Polaris installations used a 1 ½" port but this one is apparently 2".  No supports needed.  I printed at .25mm layers.
