Adapter for 50mm pvc to Emaux ST series pump

thingiverse

I've got an early Emaux ST-033 pump on my pool filter setup. It came with a 40mm barbed hose column that doesn't match anything standard, like 38mm flexible or 50mm PVC. I created this adapter to allow me to fit a 50mm standard PVC pool flexible tubing, which needs to be glued in place. The adapter's inside curvature ensures non-turbulent flow, at least if the print flaws are sanded out properly. It should slip on smoothly without any aftercare needed outside. To be glued onto the PVC piping securely.
