How to make a Bottle Buddy?

A Bottle Buddy is a useful tool that holds and sorts water bottles or other containers safely. Here is a full guide to make your own.

Materials Needed

1. Foam pipe insulation (about 2-3 inches in diameter)
2. Scissors or a utility knife
3. Tape measure
4. Marker
5. Optional: Decorative duct tape or fabric
6. Optional: Velcro strips or elastic bands

Step-by-Step Instructions

7. Measure and Cut the Foam
   • Measure around your bottle at its widest part.
   • Cut a piece of foam pipe insulation that is a bit longer than your measurement.
   • For normal water bottles, a 12-inch piece usually works well.
8. Create the Base Structure
   • If your foam pipe insulation is not already cut, slice a straight line along one side.
   • Open the foam tube and put it on a flat surface.
   • Cut a notch about 1-2 inches wide in the middle of one long edge. This makes the handle part.
9. Customize for Your Bottle
   • Test the fit by putting your bottle in the center of the foam.
   • Adjust the notch size if needed so the bottle fits tight.
   • Round off any sharp corners for comfort and a neat look.
10. Optional Personalization
    • Cover the foam with decorative duct tape or fabric to help it last and look nice.
    • Add Velcro strips to keep the Bottle Buddy on larger containers.
    • Consider adding a small carabiner so you can hang it.

Usage Tips

11. The Bottle Buddy can help keep your drink cold or hot by insulating your bottle.
12. It gives extra grip to bottles with smooth surfaces.
13. The handle makes it easier to carry bottles without their own handles.
14. It stops cold drink water from making surfaces wet.
