Found a bunch of great battery dispensers on Thingiverse like the following:
However they all had their issues. Some were difficult to print, some got jammed easily, some just simply didnt look very good.
I took the ideas of a bunch of designs and kind of combined them all into a design that I think is very easy to print, doesnt jam, and looks really nice.
Simply print one of each of the inside pieces, one set of letters and then a mirrored pair of the outside panels and use a bit of super glue to attach them. Works great, looks great, feels great.
