No excuses, this was all done with the free version of Google Sketchup. Quite a few parts were pre-made models free from the Google 3D Warehouse, with just a few mods here and there, as needed. Who would have thought the best way to find nice models of sprinkler valves would be kids drawing elaborate versions of PVC spud guns.
