My cats were constantly dropping my Magic Mouse off the table and I got bored hiding it in the drawer, so I came up with the idea of a bracket that can mount the mouse anywhere. In my case on the underside of the table where it won't collect dust and is off paws. The mouse slides in easily and grips in place towards the end. The holder can safely mount the mouse on the wall, under a table or on your foreheadI printed in ABS 0.15mm layer thickness, 3 solid layers top and bottom, 3 perimeters. It worked straight off the printer. The holes you see on the surface fill are caused by my experiments with retracting.
