Hey guys! I designed the Beverage Buddy! 

A must have for every picnic or visit at the beach.

It is detachable and stackable for easier transportation.

It fits every can/bottle up to 500ml/50cl securely! (If thin, thick, tall, small etc. does not matter!)

I'd advise printing it with 2 walls and 15% infill.

If the thread does not run smoothly, simply screw the anchor on and off a few times and it should screw in more smoothly.

Feel free to also check out some of my other designs that might make a trip more enjoyable! :)
