Modular CD holder with ejection levers

Here I present you a customizable, modular CD holder with ejection levers.
I am including a pre-assembled STL with slots for 8 CDs, but it is just an example.

This is a modular system consisitng of four (+1) separate parts.
Full CAD files are also included if you want to add your own features or for example change the shape of the lever head.

- A base with slot to accept 1 CD and one full side.

- an internal module that can be multiplied and stacked as many times as you need, the wall is cut out strategically to save filament (more on this later).

- A cover to put at the end of your stack of modules.

- A lever, which you print once per each CD slot you want.

- (A spare bit of filament to act as the commomn fulcrum and retainer for all the levers)

So how do I put it together to have more or less slots?

The dirty way is to print all the modules flat and glue them together, but lets be honest, it will stink.

The pro way is to stack the parts in your CAD softwa
