This downloadable build guide was created after so many people asked for measurements and plans for our Backyard Super Slingshot. I did my best to document the build as accurately as possible for seasoned builders and curious DIYers alike—but I’m a self-taught, beginner builder, not a professional carpenter, so consider this a practical guide rather than engineered plans. My hope is simple: to make building this thing feel approachable, fun, and easy enough that more families can bring a little backyard magic to life.
