I am seeking some advice on material selection for making a friction ball & socket clamp. The socket is clamped to the ball with a binder screw. Here is a similar example from RAM Mounts: socketball For the clamp to hold much force, the material needs strength and have friction. Is "Strong & Flexible" nylon too slippery? Is "Fine Detail Plastic" acrylic-based photopolymer strong enough? I have no experience with any of Shapeway's materials. This will be my first go at 3D printing. I Appreciate your advice.
