A few years back I created the original Display Cup and posted it here (https://www.instructables.com/Display-Cup/). Despite it not being all that practical, it did serve as a good proof of concept. It also represented that rarest of things among overly creative people like myself: a finished project!
While I had lots of ideas of where to take it next, I didn't do much except think about it for some years. I did try to make a better cup using acrylic sheet and bending it to shape, but this didnt really work very well. It was not until another instructables user inquired about the cup. He proceeded to make one himself, which was awesome and very encouraging. We have subsequently become friends as a result!
This got me fired up about revisiting this project to make a much better design. To that end, I bought something I'd wanted for a very long time, a 3d printer. Shout out to Cherry Blossom Development for funding this purchase!
Did you ever manage to get it working with a Slack bot or something similar?
