Polaroid Super Shooter 120 6x6 conversion
This back works in conjunction with the Polaroid 120 6x6 cartridge (https://www.thingiverse.com/thing:5144348) and fits onto the back of the Polaroid Super Shooter Plus. This will likely work with other plastic bodied Polaroid pack cameras as well.
To use this back, remove the old back and the wire retainer and put the retainer onto the new back. Remove the black cover over the left side of the cartridge bay. This cover is there so that the film pack will slide in, actuating the switch at the upper left. Because it won't be there anymore, be sure you slide the 120 6x6 cartridge in the same way as before, otherwise it will sit on top of the switch. It needs to slide in so it rests against the swtich.
