Looking for something amazing to 3D print? The Twistsaber is exactly what it sounds like — a lightsaber you twist to extend and retract, with an ingenious nesting screw design that makes its blade open and close incredibly fast. The files aren’t free, and it doesn’t light up, but there’s nothing else like it on the market. Just don’t expect to duel with this one! #starwars #3dprinting #lightsaber #toy #todayimtoyingwith | The Verge
