Cap Lanyard for Beautail Collapsible Water Bottle

I bought a Beautail collapsible water bottle for an upcoming flight and discovered that the lid sits loose and I held my breath every time I tossed the bottle in my bag. Love the bottle otherwise - collapses small, very functional, doesn't leak.

So, I designed a simple TPU lanyard that fits snugly over the lid and uses a zip tie style tail that loops onto the small rubber band keeper built into the bottle. No more lost-cap anxiety :)

Works great so far. I liked it enough that I ordered a second Beautail and printed another holder.

If you haven't printed with TPU yet, this is a great first project - small part, forgiving geometry, and the result is genuinely useful. A few notes:

- Dry your filament. TPU pulls moisture fast and you'll get pockmarks if it's wet. - TPU strings quite a bit. After printing, a quick pass with a lighter or heat gun cleans it up instantly. If lighter, just brush it accross the surface or you will get soot.  Bottle Reference:  Here's a link if you like (https://www.amazon.com/dp/B0CW34JH17).
