Reef Octopus skimmer pump adapter

thingiverse

The pump on my Reef Octopus skimmer died recently, and I wanted to upgrade to a DC pump. I don't recall the skimmer model, but the pump was an "Octopus Turbine Pump" model OTP-1000. I ordered the Curve 7 version of the "Bubble Magus Curve 5 Curve 7 Pump Upgrade Kits" from www.fish-street.com, but needed an adapter to connect the new pump to the union on the skimmer body. I printed the Compact Skimmer Pump adapter at 50% infill, .2mm layer height with the stock .4mm nozzle using Overture transparent PETG. I printed the Skimmer Pump O-Ring out of Overture White TPU. The threads on the union side won't tighten up enough to seal without an o-ring, but with the o-ring, I've not noticed any microbubbles leaking into the sump. My skimmers are located in the sump, so I haven't tested this fitting with an externally mounted skimmer. Be very careful if you try that.
