I'm currently working on a Instax square back for my RB67.
I've seen some folks just mount the entire Instax camera on the RB but I can't get the focus distance to work, it is to far away.
Instead I'm going for a custom designed 3d printed back wich will fit the film ejection mechanism

Some pics so far

Good luck - that looks like an expensive project. I would love to see the Instax Wide for the RB, but I am unsure if the sizing is right.

Better still, I would love for Fuji to bring back FP100.

I still have a half finished FP100 in my RB67 Polaroid back. DOn;t suppose it will work any more as the chemicals are probably shot. I might have an unopened Fuji pack. Any good?

You have nothing to lose by trying. Heck, I would give the half-used pack a shot!

Another way to do it is to put the instax film in the sheet-film holder, then use the intact instax camera for processing.

Not to expensive except for the camera and time
Wish Fuji would just sell the film ejection mechanism loose

Would you be able to share the file? I been needing only that front portion that connects to the RB67. Been trying to make a mod for my instax too!
Thanks
