Full-flow pool vaccum attachment

thingiverse

I created this thing to quickly suck large volumes of debris such as leaves, dead frogs, millipedes, and so on from the bottom of our pool. It fits into a standard pole and a standard pool vacuum hose attaches to it. The spherical end avoids damage to our vinyl pool liner. I used a spring clip from a commercial brush head as I wasn't able to print anything that would maintain necessary tension. Thing 19216 (http://www.thingiverse.com/thing:19216) may be of use here. I've been using it for about ten months; it works great! Instructions You don't want infill: This thing needs to be solid in order to handle stresses underwater.
