This is a lid for the Bodum teapot. This teapot is supposed to be used with a piston for infusing herbs, but I usually use tea in bags, so I figured I'd design and print this lid so my tea would stay hot longer. And it really helps !
I've printed it in TPU, but I guess it should work just as well in hard plastic such as PTFE or PLA. Little dents help the lid stay in place when you pour the tea, which is definitely my favorite feature.
Hop you enjoy it as much as I do ;-)
