About this 3D model

I wanted to connect a garden hose to an indoor faucet, but the connector that screws on the faucet didn't fit. I had to make a transition (though I should have made a hose connector that directly fit the faucet, maybe later). The faucet thread is M22, the hose connector thread was apparently G1/2", but I winged it and it fit, so that was good. The part I printed isn't really watertight, I printed with 2 perimeters and with 50% infill. If water is obstructed, it sprays out through this part. I have to seal it with epoxy or something, avoiding the threads of course. Perhaps it'll work off the printer if I print at 100% infill. This was made possibl by the brilliant ISO metric thread library by TrevM: http://www.thingiverse.com/thing:311031 (see my comment there for a necesary modification). Update: uploaded v2 of both files, v1 was too short and the wall wasn't thick enough for a decent infill. I also recommend 100% rectilinear infill when printing this part.
