This is a gravity-assisted screw sorter that doubles as a toolbox. It can sort nuts as well as 3 different sizes of screws: 3/4 in, 1.25 in, 1.5 in. It has removable compartments that snap fit into and out of the main sorter.

Print with supports. You might have to sand down the compartments if they have excess support material. The assembly stl is just for view, don't print it together as in the assembly, print them separately, with:

x1 sorter
x4 compartments
