Note: This, unlike many of my items, may be in limited supply as the mechanicals are pretty expensive. If you buy this item and have an Instax square camera(working or non-working is fine, but it cannot be crushed/missing parts), send it to me for a refund on the price of 50 dollars. This only applies to customers who buy this camera back at full price and after I receive the camera from you.

If you don't have the instax square camera, don't worry- I will source one immediately and it will not hold up your instant back.


 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 Instax Square film, a nice fit for this camera! It is 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. 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 3rd 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 no cropping. 







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(The instax squares work best with lithium ion batteries, but I am prohibited from sending those,so if you have slow eject, just add those batteries)!!





About me: I am an artist, college professor, creative photographer, and maker. I sell mostly Polaroid cameras, shoot mostly analog, and love to hack things. I am and have always been a huge fan of the DIY movement. I have a blog called Lo-Fi and DIY com(lofianddiy).


Note: I put 10 business days handling on my custom camera backs because I make them to order. I often come in at earlier than that time, but sometimes I experience a lot of orders(not complaining!), so I will likely need a lot of that time to get it built and shipped to you. Thanks in advance for your patience and understanding! Aaron
