Water Cooler Tank Cap - Containment Solution

I use a water cooler at home. One feature I love about it is that I can run to the store and fill up my water cooler tank for really cheap, and then take it home to load into my water cooler unit.

For those of you unfamiliar, you puncture the disposable lid of the tank the first time you use it, and then after that, the tank can be refilled. However, that puncture hole remains, as it's how the water drains from the tank into the water cooler. This is a cause for a lot of sloshing when transporting the water in my car. It means that carrying the tank becomes really awkward - I can't use the handle anymore because water would simply pour out. Additionally, if you're like my room mates and I, you know it can be useful to have two water cooler tanks to swap between when one gets low. I don't want the tank on standby filling with dust or anything else.

I have created a solution to the three problems above. Print this simple device, and your tanks will be easily plugged during transportation and storage. For the super technical creators, exposing the cap to heat while on the tank can help thermo-form it for a better fit.

Print the cap on its top for an easy, no supports-needed print. Thank you for your time, and happy printing!
