Pool Vac Hose Attachment

A remix of GA 3D's attachment (#380387), I've used his version for a couple of years and it works really well other than the fact that the bridge between the nozzle tube and the handle tube is a bit thin and susceptible to breaking, and I also found that the nozzle lips were a little sharp and I was worried about catching it on the liner joints so I ended up sanding it down a bit.

The remix addresses both of these issues using a thicker bridge section with filleted joints to the two tubes to reduce stress points, and rounded lips on the end of the nozzle and handle tubes.
