Soda Bottle Spout - Water

myminifactory

Maintaining proper hydration is crucial when participating in sports or other strenuous activities. Wearing a helmet or heavy equipment can sometimes make it difficult to access the top of a water bottle. These spouts screw onto the top of a standard soda bottle, allowing it to be reused as a no-touch water bottle for sports and other activities. It includes a loop at the back for attaching a hanger or handle. This version has the word WATER embossed on the support/flag to help distinguish it from other liquids being hydrated with, or to keep it from being used in other bottles to avoid cross-contamination. The threads are based on a normal soda bottle (the PCO-1881 beverage bottle thread standard), so they should fit on just about any standard plastic soda bottle. This includes 1-liter, 2-liter, 24-ounce, and 16-ounce bottles. I have published several variations on this design, including one with a blank flag for adding your own label, and one with no label area to save filament and print time. I've also included a short version for use with printers that have smaller printbeds or for users who want to spend less time and filament printing them. The prints will need a couple of standard off-the-shelf parts for completion: one food-grade hose washer per spout, which presses into the bottom of the threaded portion of the spout to seal against the neck of the bottle, and a short length of food-safe 3/8" tubing long enough to reach the bottom of your bottle. Assembly and Use: Trim off the small round feet at the end of the nozzle - they're just there for extra bed adhesion. Assemble the pieces as shown in the photos, fill your bottle with water, and screw the spout onto the threaded neck in place of the bottle's cap. A good firm squeeze on the bottle should result in a stream of water from the nozzle. Recommendations: Print with more perimeters than usual to prevent leakage through gaps. Set your slicer for a bit of over-extrusion to use more filament and fill gaps between layers. Print these without support, or your slicer might try to fill the water channel with support material. If you decide that you want supports for the hanger loop at the back, use settings to generate only printbed supports. Food-grade hose washers are commonly available for use with recreational vehicle utility hookups. Look for them wherever RV accessories are sold. Although most contact is limited to the bottle and dip tube, water will be flowing through the printed nozzle during use, so choose your filament accordingly. Be sure to rinse and dry your spouts thoroughly after use.
