Received an awesome equal space divider as a gift, but being that it was used, it didn't come with a case. So I made a case! The divider measures about 40 mm x 160 mm x 2.40 mm. Made a representative model called 'divider' which you could print a shelled out version of to compare to your own divider.

Keep flat surface down on build plate and use supports for hinge and lock mechanism. Print lock with ridges facing up, and should be able to print without supports if printer tuned properly.
