This project is inspired by Jason Klass "A DIY Cap Keeper for your DIY Water Bottle"
This is a great idea and I did try to make one but my zip tie keep popping off when I use the cap keeper as a bottle holder. Even with liberal amounts of super glue.
This is an improvement I'm calling it the DIY Gatorade Cap Keeper
Step 1: Supplies Needed
About 1 foot of Para cord
Step 2: Tools Used
Mini vice grip (or anything so you can work with the hot awl type tool from the heavy coat hanger)
Heavy kitchen scissors (any sharp scissors will do)
Small utility knife (razor blade)
Heavy duty pliers (I used a metal hand break)
Gas Stove (any stove will work as long you can heat the coat hanger
Step 3: Ok Lets Begin
Step 4: Step 1
Step 5: Step 2
Once the awl is really hot, just before it turns red hot then its hot enough to melt a small in the middle of the first cap
Step 6: Step 3
Step 7: Step 4
Tie an over hand knot as a stopper.
Once you have that done you will need to smash the knot as flat as you can. This allows the 2 caps to fit closer to each other.
Step 8: Step 5
Now fit the 1st cap with the Para cord installed onto the 2nd cap.
Heat up the heavy metal coat hanger and then weld/melt the first cap to the 2nd cap. Make sure you do not melt through the 2nd cap.
Heat up the heavy coat hanger and repeat all around the cap.
When you have worked all the way around the cap you should have something looking like this.
You can use some sand paper to smooth all the rough places.
Step 9: Step 6
That’s it your all done. This is strong enough to hold the large 1/2 gallon bottle.
