Better Cooler Drain Plug (RubberMaid Cooler) with o-rings.

I lost the plug for this darn cooler long ago, in a galaxy far far away. Since then I've made several plug replacements. I even made one out of duct tape! This time I decided to finally make the plug to end all plugs and design and 3d print one. So this is my latest iteration. I'm confident to declare that **you can not buy a better plug** for your cooler than this. It's better designed and better made than the plug that came with the cooler and it's also better than the replacement plugs
