bottles_preview_featuredIn the workplace, at parties, is there anything more irritating/potentially disease-causing than someone else drinking out of your beverage? Sure, you can put your name on your water or soda bottle with a Sharpie, but it smudges, and gets all over your hands, and more often than not, people ignore it anyway. I always appreciate when a party host has wine glass charms – they’re classy, pretty and usually keep people away from my Pinot Grigio, but when it comes to bottled beverages, it’s still a free-for-all. Don’t you wish there was a surefire way to not only clearly mark your drink as your own, but to scare potential thieves away from it?  Now there is – with 3D printed Bottle Monsters  by German Thingiverse user David Hagemann.

“Are you sick of people drinking out of your bottle?” Hagemann, a 3D artist and game developer, demands. “Or are you even literally sick because of people drinking out of your bottle? Print a Bottle Monster and it will protect the liquid of your choice simply by plugging it on top of the bottle!”

Bottle Monsters can be screwed onto the top of any disposable beverage bottle, and come in three bottle monsterversions: Aaaaaahh, Biiiiiiih and Ciiiiiiih, which all look ready to bite the hands off any thirsty, thieving human that may get too close. The design was a remix of a basic bottle cap design by user Joris Bijnens. The monster can be detached from the bottle cap adapter for other uses, which include, per Hagemann’s page:

  • Putting it on top of your yogurt so nobody eats it.
  • Putting it on top of your monitor so nobody looks at it.
  • Putting it in front of your window so nobody breaks in.
  • Putting it in your car so nobody steals it.
  • Putting it on top of your head so nobody looks at you wrong.

Bottle Monsters are printed in several parts and require some simple assembly once printed, and can be airbrushed in whichever colors you think will strike the most fear into the hearts of your Coke-stealing enemies.

“I used Model Air Paint, acrylic based airbrush colors,” says Hagemann. “To give some insight in how I painted them: First a dark red layer, then some slight hue variations in different areas, mostly yellowish and bright red. On top of that a slight bright saturated green layer with a good amount of thinner.”

bottleBottle Monsters are a great idea for children’s parties – if the threat of cooties isn’t enough to keep them away from each other’s drinks, there are few things that kids take more seriously than monsters. Now if only there was a version that would fit over a Solo cup.
