Curved Cliffhanger (10.00"): Ninja Warrior Series

thingiverse

Inspired from the TV show "American Ninja Warrior," this hold imitates the famous cliffhanger ledge, which can be found in nearly every season of both ANW and Sasuke (the original Japanese version). A cliffhanger hold is a small rectangular ledge that competitors traverse. However, this version is a bit different--by adding curved lips to the top and bottom, it is a bit easier to grab (and perfect for younger ninjas who'd like a challenge!) This design of cliffhanger is ten inches long and roughly 1.75 inches deep--the optimal beginner cliffhanger. Its curved lips provide a surface that's much easier to grab, which can help with the transition from curved to straight ledges. (For a shorter, five-inch ledge, please see my design page.) To secure this ledge to the wall, you can use either 3/8" lag bolts or hex bolts. (Keep in mind that 3/8" hex bolts and 3/8" washers are necessary for the hex bolt option--see the above image.) Lag bolts are permanent, whereas hex bolts can be taken out and changed if need-be. As this is a deeper cliffhanger, longer bolts are heavily recommended--3.5" lag bolts should do the trick. Overall, the cliffhanger is one of the most challenging obstacles in the entire sport of ninja warrior, and the slick material of PLA only increases the challenge. To add more grip, chalk can be added to the outside of the ledge--it will naturally become wedged in the layer lines of the print, which can make the cliffhanger easier and more grippy. And that's all! Simply attach the cliffhanger to a wall and get hanging!
