3D model description


This one is something classic.A 8 bits invaders generator.

With Customizer you can create a full fleet ready for print in one file.

As a random generator, it depends of a numeric seed (up to 19 digits). Every seed creates different invaders.
Try different seeds until you get a nice one!

Each generation produces three files: The 'invaders', a base or support that fits, and a third file with invaders and base together.

Some examples and info about customization in images below.

Also added the 3 STL's used in printing tests (seed=123).

Have fun!!

Tested with PLA.


Infill acts as inner supports avoiding holes in top of figure. Recomended a 10% or 15%
