That looks quite good Burr, and it allows for creating it as a larger "sheet" of stuff.

Will that method work for you Tony?

But really if you're mostly concerned about file size, then using an instancing feature in your rendering program is probably the way you would want to do it - many rendering programs have some way to replicate an object where it does not fully copy each separate one and instead keeps it as a lightweight instance of the main one.
