I think there is no better pinhole camera than anamorphic 617 pinhole camera. I think if it would cost less than 50 dıollars to print it , its viable option. I dont see any reason to print above camera also. I think printing is a investment to hand craft like pieces , may be an gaudi handle and
3d printed acrylic anamorphic lens. Otherwise , that cant compete with any camera present.
I agree with AgX.
