Lay-Z-spa garden hose adapter

A friend of mine didn't have an alternative pump to empty his lay-z-spa and asked me if I could make him an adapter so he could use the lay-z-spa pump unit to pump the water through a hose pipe and into a near by drain.

the adapter screws directly into the water outlet inside the spa (you will need to unscrew and remove the diffuser first).

printed at 0.2mm resolution with supports, do not support the screw thread, just the 90deg overhangs. If my memory serves my right I printed this at 20
