The print quality of these adapters are very good. As a 3D printer fanatic myself, I can safely say that these prints met and exceeded my expectations. Two are included in the kit. It's a really tight fit, but M2 screws are needed to mount the sides, and the provided screws will mount the Nano 3. Beware though, that the Nano 3 might be discontinued, since the factory that made the lenses went bust recently. Overall, if you want to mount your Nano 3 in a 14 x 14mm form factor, this is the only and best place in my opinion to get it.
