Pond/Hydroponic Pump Hose Fitting

Bought a pump off Amazon (this one specifically, 45w version) to build the awesome Hydroponic Tower by Dextera (here). Unfortunately the cheap pump i got had a fitting that was basically unusable for me and didnt fit (the threads were somehow way too small and it just flopped around in the pump outlet). The original black fitting it came with is shown in the last provided picture so you can see how far off the size was. I designed this hose fitting and the tolerances fit perfectly for this specific pump (Teemo branded). It has the following measurementsThread pitch: 1.5mmNozzle OD: 13.5mmThread OD: 20.9mmFeel free to remix or change as needed if you like. I'm still learning how to use Fusion360, but if you'd like my original design file just reach out.
