Under Shelf Cup Holder

thingiverse

A simple holder to hang plastic cups from under a shelf so my kids don't need to get them from cupboard that's too tall for them. Tweaking the parameters in the included OpenSCAD file you can generate your own for your particular cups size/weight. As the cups we use are very light, I didn't even bother to use screws, double sided tape was enough. I didn't test with glass cups, but I'd bet it can work just fine using screws and maybe increasing the cone height -- let me know if it works for you, make pics appreciated.
