Space Invaders Fleet Generator

thingiverse

Hi! This one's a classic - an 8-bit Invaders generator that lets you create a full fleet ready for printing in just one file! With Customizer, you can generate different invaders every time, each with its own unique design. Just try different numeric seeds (up to 19 digits) until you get the perfect combination! Each generation produces three files: the 'invaders' themselves, a base or support that fits perfectly, and a third file combining both. For an extra smooth fit, we recommend using Flow Calibrator. Check out some examples of customization in the images below! We've also included the 3 STL's used in our 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 the top of the figure. We recommend a 10% or 15% infill for best results. The size of every 'pixel' is 5mm, and the height of the base is 5mms with a flat bottom of 1 mm. Due to this design, each invader is 4mm high. Customizer Examples: A 6-invasion Fleet with separate bases for each A massive fleet made up of 5x5 pixel invaders A huge one! Invader strip - all invaders share the same base Inserting Invaders into Support: If your invaders are larger than the holes in the base and they don't fit, try: Software tools: Adjust your printer's flow using Flow Calibrator. If your slicer software has a 'Horizontal Expansion' parameter (Cura does), use it to make a better fit. Hardware tools: Pliers are your friends! And if all else fails, Murphy says to try with a hammer - it works, tested! You can also apply hot water and push carefully. Cura's 'Horizontal Expansion' parameter may be useful for an easy invader-base fit.
