water pump adapters
thingiverse
I designed adapters for a standard water pump available on eBay, AliExpress, or Amazon. I have thoroughly tested these adapters and found that they securely attach if printed at high resolution. To achieve an optimal seal, I suggest utilizing an O-ring if you have one available. The thread is M20-2mm in size. The adapters are designed for use with 0.5-inch tubing (the outer diameter of the fitting is 0.375 inches). These sealed effectively during my testing.
