LED Matrix Modular Case System

I have designed the following modular parts for constructing cases for the popular cascadable dot matrix LED display modules

The MAX7219 Dot Matrix Display Modules I used measured:-
130mm x 32mm x12mm (all approx.)


The design can accomodate any number of these modules by stacking the case parts in various ways.

e.g.

For a single module you can use either:-
A middle section + 1 male end cap + 1 female end cap.
OR
1 Male end + 1 Female end.

For two modules you can use:-
A Middle section + 1 Male end + 1 Female end.
OR
2 x Middle section + 1 Male end cap + 1 Female end cap.

For Three modules you can use:-
2 x Middle sections + 1 Male end + 1 Female end.

etc.


The parts 'click' together by using a tongue and groove system (male = tongue, female = groove).

As designed, the parts print on a Vertex 8400 printer with a 0.35 nozzle and fit together nicely.

The case parts have a slot for the LED modules to slide
