I really dont know, I assume one wouldnt build the entire scales from it, but perhaps a basic scale-blank, with the sugru moulded over it to give texture, grip etc.

Sugru is some sort of mouldable silicone rubber, that sets to its shape, and is very hardy, grippy and easily cleaned.

Has anyone experimented with 3D printed scales, or building / shaping scales with Sugru?

I have seen posts about creating from wood etc, but didnt see anything about 3d printed.
