No, it’s not a device for making rodents confess.
I use a MacBook Pro as my main computer, and I really love the trackpad. I only use a mouse for gaming and the occasional bit of high-resolution CAD work. I have really limited desk space, though, so the mouse was often unused but in the way.
This dirt-simple print (I don’t think it took me five minutes to design it in FreeCAD) lets me stow the mouse out of the way when I’m not using it.
