Moen pull down faucet to garden hose adapter

thingiverse

Bought an aquarium vacuum that harnesses the power of faucet water flow to initiate the siphon. Our Moen Pull-down faucet is quite elaborate, but none of the included adapters fit snugly onto the hose where the sprayhead unscrews. Thanks to the keen eyes of some home brewing forums, we discovered that the connector requires an M16x1.5 thread. I managed to design a custom adapter using Tinkercad and modified another one to create a garden hose fitting, which is the primary attachment point for the vacuum.
