This is basically the same thing as my 1x1x12 quad window bin, however i have added a center diagonal divider to make it a 2 compartment bin. The center piece has a slight recess that allows the microscope slide to go into the base plate so there is no gaps at the bottom between the slide and the base plate. There are two versions, one with room at the top for standard 0.5"/12mm labels and one without. All you need is about 30 grams of pla and 5 microscope slides. Happy Printing!
