Rowenta Thermos lid repair

thingiverse

I'm absolutely thrilled with my Rowenta coffee machine - the flavor of the coffee is simply sublime. However, after just one year, I've noticed that it consistently experiences a critical issue: the coffee refuses to flow through the lid. This is all due to a stubborn ring forming at the bottom of the lid. Unfortunately, since you can't purchase a replacement lid, my only option is to buy an entirely new thermos for 20 euros - not exactly a budget-friendly solution. This predicament has me searching for alternative options that won't break the bank.
