A spacey Springo for wobbling through the universe! For best results, print at .15mm layer height with 100% infill. You may scale this by proportionately changing layer height. Prints without supports, just carefully pry the Springo apart after printing! I personally only split apart one of the two helical cuts so the rocket is more springy than floppy (and I was scared of breaking it!)

If you've got a giant printer, combine this with my Rocket Smoke model for an impressive display!
