Wet Vac to HVAC adapter v2.0

Every year I drain the Air Conditioning condensation line and each time I think about making this adapter because the standard vac hose diameter and the AC line elbow don't match.

Simple utilitarian piece of 3D printing...

v2.0 is thicker, shorter, stronger and quicker to print with a hexagonal ring in case the adapter gets stuck and you have to twist it out.
