Cup and Balls Trick Cup

thingiverse

Wanted to print a set of cups for the classic Cup and Balls magic routine and didn't find anything that I liked, tried a couple and they didn't work well, one version even thought that cups that LOCK together was a good way to do this trick... NOT!!! The cups must freely separate when one cup is lifted off of the stack of nested cups, cups that STICK together are not the way to do this trick. I use 25mm (1 inch) foam balls commonly available on Amazon and other sites, much better presentation than the "furballs" or "hairballs" that commonly come with the commercial versions of this trick. There are plenty of videos showing how this trick is performed on YouTube and other sites, print 3 get some foam balls and have fun! Common drinking cups will not work for this trick, the cups need to be designed so there is room for a ball to fit in between the cups when they are stacked. I found a Customisable SCAD file that would generate cups in just about any size you want, here is a link to it: https://www.thingiverse.com/thing:2936229, Thank You by rhtndnjs03 !!! I generated a cup that I though would work, took the STL file into Tinkercad and modified it to meet my needs and here is the result, hope you enjoy it and you can use to entertain your friends, family and total strangers. I love magic! I was a magician when I was younger and slid off into the tech world for a few decades and have now come full circle.
