Space Invaders Fleet Generator

thingiverse

Hi! 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. 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!! Print Settings Printer: BQ Prusa i3 Hephestos Rafts: Doesn't Matter Resolution: 0.2 Infill: 10%-20% Notes: 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 Customizer examples A 6 invaders Fleet with separated bases for everyone A huge fleet made of 5x5 pixels invaders. A big one!! Invader strip. This one has one base for all invaders. 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. 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. 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
