The design models have been 3D printed and assembled. We made two devices, only the outer casings are different in the two models. One is printed on a SLS 3d printer (Nylon PA-12) and another one with an FDM 3D printer (PLA Black).

Both the models are working fine and were able to capture decent retinal images.
