Space Ships!
thingiverse
20 spaceships print out at once. This will get you an armada quickly. They make great little toys for kids. My kids use them as replacement pieces in board games, as well as making fun "space armada battles" with some imagination. "Pew-pew-pew" sounds sold separately (make your own). Instructions The STL file will print 20 of these, in 3 rows, to fill the build space of a MakerBot Replicator. The last row is a set of slightly smaller ships. If you wish to get the blender (source) file, I'd be glad to share. Just contact me at john@gophoto.com.
With this file you will be able to print Space Ships! with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Space Ships!.
