About this 3D model

It prints OK... threads onto typical U.S. garden hoses. Leaks like none other without a washer. I haven't been able to make the printable washer work well with PLA or Layman wood fiber... I haven't tried soft-PLA yet, but it might be worth a shot. (FWIW: My troubles with soft-PLA prompted me to investigate a specialized extruder mod like this: http://www.thingiverse.com/thing:147472)
