One of the first things we designed when we got a 3D printer was a replacement cap for my growler. It broke when I was moving. Marie made the initial models in TinkerCad, and I refined it a bit in the wee hours of the morning.
I’ve printed multiple iterations of it, so I thought I’d see how it does in TPU. I’ve been having such fun with TPU recently. This iteration proved to be a little flimsy on the one tap, but it looks pretty. I suspect I’ll eventually land on some hybrid solution: a strong crossbar to apply preasure, and maybe some TPU for the seal.
