Tumbler Cup Handle

thingiverse

I used Tinkercad to make this thing. I've got some tumbler cups, and I want to create handles for them. This is the standard size, so let's see how it goes. My goal is to print it out over the weekend. The first try didn't go well at all – no give whatsoever. So, I added a hollow notch that lets the ring expand and grip tightly in place. To top that off, I lengthened the handle significantly. And it seems to work beautifully so far! Now, I just need to test it thoroughly before calling it good.
