3D printers have recently become cheaper, more reliable, and more capable at the consumer level. On the same token, photographers constantly need all sorts of miscellaneous parts: adapters, clamps, rings, etc. It seems like now is the time for at-home 3D printing to take hold.
I stumbled across these plans for a Kiev 10/15 to Sony E-Mount adapter recently. It allows these lenses to be mounted onto any Sony E-mount camera and maintains infinity focus and aperture control. Older Soviet lenses are known for being a treasure trove of interesting optics that are built like tanks. However, finding adapters can be both difficult and pricey at times. The ability to 3D print such devices at home is very enticing, and it could be a great boon to those of us who are constantly losing accessories, like to experiment, or who simply need parts that don't exist.
Imagine finding a neat lens and wanting to try it on your Canon: design an adaptor and print it yourself. Need a memory card case? You can get that here. Labeled lens caps? Someone designed those. Lost your lens hood? That's right here. Try tilt-shift photography for cheap here. The best part is that many of these designs are free. Of course, there are some limitations: robustness isn't guaranteed, and pretty much anything requiring a circuit board is out, but both the convenience and creative possibilities are promising.
