I have dropped my Contigo tumblers multiple times and they are usually just fine. Once in awhile the ring around the button pops off. The button doesn’t quite work right without the ring and I usually just glue it back on. This last time though, the ring went off on an adventure of it’s own, either to retire on a sunny beach, to search for someone with different drink preferences, or to find a less abusive home
Never fear! I have a Glowforge!
I measured the remaining hole with my trusty calipers and got to work in Affinity Designer.
The resulting design works just fine and is on the left side of the svg, but after I tried it, I did some tweaking to make a better fit at the top and this is on the right side of the svg. The modified version has not been tested yet. The 2 versions of the ring are in the svg - just ignore the one you don’t want to use, and ignore the text as well. The zip file has the Affinity Designer file if someone wants to adjust it further.
The Contigo lid is not flat, and you will need to heat up the acrylic and bend it. I bought this set from Amazon and both of the tools worked perfectly when I used them.

The tools come with some anti stick stuff to add to the flat one, which I found I needed for this very small part.
Please be careful. This is a tiny bit of acrylic and will be hot and there is no cool place to touch it to make it form just the right shape. I braced the lid in a good position and poked the heated acrylic ring with pliers, tweezers and a few other tools I could grab quickly once I found out how hot it was
Once the ring cooled to the right shape, I glued it in (some sort of super type glue I think). Do not glue the ring to the button. The ring is there to make the button move straight in and out.
The 1/8 proofgrade acrylic stands up a bit higher than the original ring, but I don’t see a problem with the functionality.
I hope this helps someone!
