UBO - the Unknown Bottle Opener

thingiverse

Looking for a bottle opener that defies gravity? Meet UBO - the Unseen Bottle Opener, designed to open bottles out of this world! This intergalactic tool is the ultimate party favor or BBQ accessory, perfect for any occasion when you need to crack open a cold one. I created UBO specifically for Alien3D and his incredible UFO Mystery boxes. Each box contains 20m long samples, allowing you to print UBO with just one piece of filament. To bring this cosmic bottle opener to life, you'll need: A reliable 3D printer About 15-16m of filament (less than 50g for PETG or PLA) One US penny or a 2ct coin (€) - or any other metal disk smaller than 19.6mm in diameter and 2mm thick To insert the coin, pause the print at 3.0mm layer height (after layer 15 with 0.2mm layer height). Place the coin in the hole and resume printing until completion. That's it! No raft or brim required, and no supports needed either. Enjoy your out-of-this-world bottle opener!
