Pipe 38mm Fitting

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 PRUSA I3 MK3S printer.

I hope you can find this print useful, too.
