Saturn Scale Model

thingiverse

A Saturn model with rotating rings (why not?). It's mostly accurate, in relation to itself: -The shape of planet is accurate (polar radius relative to equatorial) -The diameter of rings relative to the diameter of planet -The angle of inclination relative to the plane of the ecliptic. -The relative dimensions of the major rings, A, B, and C. The thickness of the rings is completely bonkers, but then you could not print the thickness accurately without approaching atomic levels (they're 5-30m thick in reality, vs a radius of 136,775,000m), at which point I'm fairly certain your extruder would jam. Instead, I've translated the relative brightness of the rings into thickness to approximate their appearance, especially if you use translucent filament. To make: -Print one of each part. -Try printing the ring in translucent plastic -The ring should be printed at 0.15mm layer thickness. -The planet halves can be printed at whatever thickness you can tolerate, the smaller the prettier. No supports required. -The resolution of the joiner piece doesn't much matter. -Assemble and glue the planet halves together with the joiner with E6000 or other glue. Don't get any glue on the rings, so they can rotate. -Screw in an appropriate eye screw to attach to a keychain I've included the OpenSCAD file, for those inclined to adjust dimensions.
