Space Invaders Fleet Generator

Hi!

This one is something classic.A8 bits invaders generator.

WithCustomizer you can create afull 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 generationproduces three files: The 'invaders', a base or support that fits, and a third file with invaders and base together.

Recomended: Flow Calibrator (http://www.thingiverse.com/thing:1662342) to ensure the invaders fits in the support.

Some examples and info about customization in images below.

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

Have fun!!

Inserting invaders into support

If Invaders are bigger than holes in base and they don't fit try:

Software tools

Adjust the flow oy your printer. TryFlow Calibrator (http://www.thingiverse.com/thing:1662342)

If your slicer software have an option to control the size of polygons (Cura has the 'Horizontal Expansion' parameter) you can use it to make a better fit.

Hardware tools

Pliers are your friends.

Murphy says: if don't fit try with a hammer. (it works. tested!)

You can also apply hot water and push carefully

Cura 'Horizontal Expansion' parameter may be useful for an easy invader-base fit
