Instax Mini Film fits 2 1/4 x 3 1/4 Film Holders!

On my film holders there was a small ridge under the flap in the area of the dotted line. I shaved that off so the flap closes without touching the development pod.

Anyway you can take a photo of the bottom of the flap?

Thanks.

I did it, it now fits but I think I cut off a mite too much because now the slide won't lock the holder. Yay. A bit of tape should sort it out though.

Reviving an old thread here but I recently came into a Busch Pressman 2 1/4 x 3 1/4 so I am looking into various ways of using it with materials available today.
I tried a two test shots today. Neither came out but I wanted to share results here for science purposes and possibly as an example of what not to do.
I am using an older unbranded wooden holder that came with the Busch Pressman.
I tried using the filmholder without modification.
It was tight, and I think likely burst the the development pod.
I am processing by manually feeding the instax through the rollers of an old Polaroid 600.
There are three exposures in the image below.
White wasn't exposed in camera. I pulled it out and exposed to light to have one to dry fit into holders and to send through rollers as a test. Not sure what I did to upper right corner.
The two following were both shot in camera, but I think the pod had burst before exposure due to pressure in the holder.
I am going to try shooting with the instax inverted, pod up, tomorrow. I am trying to avoid having to modify the holders because I still use them for sheet film and paper negatives.
Thanks to everyone from 4 years ago that was messing around with this and made me aware its a possibility.

I might suggest modifying the flap and using an Instax camera for the development.

I have exposed perhaps 100 Instax films in the Fidelity film holders. In fact, I recently got two more NOS holders. Now I have five, enough to hold a ten-pack of film at once.

This thread was started in 2017 and all these years I have not bought a dedicated Instax film back for my camera because the bulk and the film plane offset outweigh the advantages. Not to say I won't ever get one, though.

Maybe someone upgraded the original Fuji Instax camera to simply insert sheets filmed by another device into constantly rotating processing part of the device?
In the 60-70s there were these in washing machines to squeeze water out of laundry...
It seems easier at once to process, not to load film sheets back to the cartridge
