    Re: Show your 3D printed LF photography related thing

    Interesting designs. I love the options of keeping obsolete format cameras going. I recently picked up a 180. I have sandwiched both Instax wide and 1/4 plate film in an old holder, works well. So the question is, are your films holders (not the 4x5 version) designed to fit quarter plate film size? If so I thought it would make a great hand held quarter plate camera.

    The Polaroid pack film sized film holders are designed for 4 1/4" x 3 3/8" paper. I'm sure the design could be modified to hold one 1/4 plate with a dark slide.

    Hi Jim. 1/4 plate is 4 1/4" x 3 1/4" though some old FP4 sheets I have is measured out as 4 1/8 x 3 1/8. A septum I have to hold the film in the holder has rails that make an image opening of just under 3" on the short side. I think your design should fit 1/4 plate film if rails to hold the film are wide enough in the current design.

    On Thingiverse I saw that you have a holder design that only requires a dark slide to be made. How does that compare with the one that just has the parts to 3D print the basic holder frame? The link to that on your site results in a 404 not found.

    Thanks

    I don't know anything about plates, but imagine they don't bend. This film holder requires a medium that can bend to get it into the holder. How thick is the plate? Maybe the holder can be designed so the end piece hinges, but then that would invite light leaks. And, the space for the negative is only as thick as a bit more than a piece of photographic paper.

    The difference between the 2 holders on thingiverse is the more complete one has the body of the holder printed, which takes quite a bit more filament. The rails build the same holder, but require some mat board, etc. to complete.

    I'm talking about sheet film in quarter plate size, not glass or metal plates. Adox still do this size and Ilford may in their annual special size format run.

    Haha, ok, shows you how clued out I am. The holder would need the borders modified to work with 1/4 plate but that certainly wouldn't be hard to do. I just cut down 5x7 film which makes 2 Polaroid sized negatives. A little tricky in the dark, but I'm getting used to it.
