Lo-Fi custom instant back Mamiya RB-67 I-type, 600, sx-70 uses aaa

Description

This 3-D printed back is an opportunity for you to maximize the versatility of your
Mamiya RB-67.
This is one of my custom "Lo- Fi" designs for your creative enjoyment. It allows you to shoot
Polaroid Originals I-type film, 600 film, and SX-70 film!
I designed it so the camera has no clearance issues like some backs. This back allows you to set your camera down flat on a table without removing the back.
It is also dialed perfectly into the film plane so you can use your rangefinder/ viewfinder
of your choice
to take your pictures. It uses four aaa batteries, so the film doesn’t need an internal battery. This is handy with old film that may have a bad battery, and also the cheap and common I type film. The eject button is just a momentary switch so you just hold it down until the film is ejected and then release the button. This takes some getting used to, but by the 3
rd
pack I was perfect at it!
I reinforced the mounting lugs for a perfectly tight fit that is really strong. I printed solid tops and bottoms with fill at 50 percent(much more than the average 20 percent fill that typical 3-d objects are printed).
Unlike some instant backs for RB67, there is very little cropping. I opened up the inside so the only limit is the camera itself(you will see little “bracket” looking cutoff in corners)!
I have included a pack with used/bad photos so you can practice your ejection skills before you mount the back- just eject and reload until you are comfortable with the eject. The back is pre-loaded with batteries and I included some fresh ones- have fun!!
