Have you ever seen a hanging pencil holder? Here you go
Ahhhhhhhhhhhhhhhhhh yes!
It is simplest invention/contraption . . .
Here, an eight-year old boy invents what I didn’t know I needed, by riffing off of two paper clips, some tape to hold it down, and a small Post It fashioned as a nest for the pencil.
The hanging pencil holder stays in place without the calculator atop its mount (which is how I first found it when I put the calculator back in its place).
