That's what I'm wondering too. Spec wise their stuff is comparable to typical plastics in terms of elasticity, tensile modulus 1.7 GPa (see https://en.wikipedia.org/wiki/Young%...oximate_values) So if this part can be done in plastic, it can be done on a 3D printer. I'm sure it's good enough to support a camera without bending/breaking, but it might cause visible shaking while riding.
