The parts required for converting the Polaroid 110 into a 4×5 rangefinder may be bought as the complete kit, with all 3d printed parts, required screws and springs or only the free STL files for your personal printing and where you need to source the other parts yourself. Or the one-stop-shop solution, where you send me your Polaroid 110 for modification, and I will return to you a converted and tested camera.

The Polaroid 110 to 4×5 rangefinder conversion starts with a complete functional Polaroid 110 A or B (Polaroid 120 should be ok also), which you need to obtain yourself. (Ebay has been my source). Please read the entire description of the conversion before you send email regarding any purchases related to the modification, although I’m more then happy to answer any question you might have.
