3D printed screw-on holds. A bundle of Ballers 1-3. Includes 3 each of S, M, and L sizes. Many of these holds offer good grip, but you can also enjoy the unique hold surfaces that come with spherical shapes. Combining two can also be used as pinch holds (photos 14 and 15 show examples of installation). Friction processed. L: W100mm D100mm H49mm M: W85mm D85mm H42mm S: W70mm D70mm H33mm Made of PLA Recommended angle: 90-120° 3D printed holds are hard and light, making them durable. They will soften at temperatures above 100°C. This shouldn't be a problem during normal use, but please be careful in a car during the summer. Also, over-tightening with an impact driver can weaken the area around the screw holes due to friction heat. Please avoid excessive tightening.
