This is a plug designed for Yeti coolers. All types of Yeti coolers use this same plug, so it’s compatible across the board. After printing, you should add a rubber gasket with dimensions 35x20x2.5 mm.

If you’ve lost your original plug, you can use this model as a replacement. Or if you simply want to replace the current one, it works just as well. Printing with PETG is recommended for better insulation and water resistance.
