You will need to do something about the sharp edges of the plastic where you cut out the side of the jug, making a hole for your hand, or it will scratch and cut your hands during use. I used narrow strips of duct tape to wrap around them -- it's easy and the tape is waterproof, so it should stay well. There may be more than one way to go about this, however: you could use hot glue (which may or may not stick to the kind of plastic you are using), or maybe Sugru, if you have some around. One thing to consider here is whether you want to do this now, before the jug is mounted on your bike, and it's easier to manipulate it, or after you mounted it, so that you can make adjustments to the cut to best suit the position of your hands. I chose to do this early on and had to re-tape after making final adjustments.



In order to make the wind guards stable, you will need to secure them to your handle bars with more than just a zip tie around the top. Hold them up where they will be mounted, so that they enclose the handle bar tips, brake handles, and whatever you have on your handle bars, while leaving a space for your hands to enter. There's usually a hole in the grips at the end of your handlebars. Use the permanent marker to mark where that hole lines up with the bottom of your jug. This is where the screw will go. Use a sharp implement to start the hole (the tip of your exacto-knife, or an awl will do, or you can use a drill). Then take the screw and screw it in a little bit.



Thread your zip tie through the holes in the "petals" around the mouth of the jug. You may need to partially pull it out and thread around brake and/or shifter cables before tightening it.
