Pipe Fitting 38mm (1.5in)

My Aquaplus Submersible Pump comes standard with a 50mm (2in) hose fitting. Unfortunately, my existing 38mm (1.5in) pipe will not slip onto the 50mm fitting. My approach to fix the pipe size mismatch was to replace the 50mm pump hose attachment held by two bolts with a 38mm fitting of my own design. This is my 3D design. My print is made in NYLON 1.75mm Polymaker black filament, with 0.2mm layer height and 15% infill on a Bambu X1 Carbon printer. No supports required. I hope that you can find this print useful, too. Remember to leave me some feedback or even a tip to keep me enthused to make more of these drawings.
