Submersible Pump 3/8" Hose Adapter

I printed out a Modular Hydroponic Tower, which was designed to use tubing with a ½" OD, 3/8" ID.

However, the submersible pump I purchased only had hose adapters down to a ½" ID, which was too large to fit my tubing. So, I designed a screw-in adapter to fit the threading of the pump and output to a 3/8" nozzle.
The threads fit my VIVOSUN Submersible Pump perfectly, and it inserted easily and securely into my 3/8" ID tubing.
(Note: I haven't tested it with other pumps, so if you try it with yours and it does or doesn't fit, please let me know so I can update the description.)

As the part is intended to be submerged, it's recommended to print in PETG. No supports or brim needed.
