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).
BQ Prusa i3 Hephestos
Tested with PLA.
NO SUPPORTS !!!
Infill acts as inner supports avoiding holes in top of figure. Recomended a 10% or 15%
The size of every 'pixel' is 5mm. Height of base is 5mms and has a flat bottom of 1 mm Due to 1mm bottom, invaders are 4mm height
Inserting invaders into support
If Invaders are bigger than holes in base and they don't fit try:
Adjust the flow oy your printer. Try Flow 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.
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
