Ok let's get started by fitting the Nozzle and its Extender Tube to the CD Case.
Cut the smaller nozzle end of the Orbit Watermaster Nozzle at an approximate angle according to the pictures, so that it sits closer to the CD Case when gluing. Start the hot-gluing by putting a dab on the side of the CD Case and sticking on the Nozzle right away. Keep hot-gluing around the Nozzle, letting things cool a bit as you go, but keep the Nozzle lined up as far as angle and direction, similar to pictures. Leave the area directly in front of the Nozzle free of glue, so that you can cut out the Case to fit an extender tube from the Nozzle into the Case. (See pics.)
A Later Note: My newer instructable
makes this nozzle install process much easier!
