Processing 9x12 Film in the SP-445/SP-645

[tim48v]

Believe it or not, people are still shooting 9x12 film. And they're still asking if they can processes it our film tanks. In fact, they started asking before the first SP-445 even shipped!

While a 9x12 film holder would be the perfect solution, the market just isn't large enough to justify it. The best answer we've had so far is to modify an original Rev 1 film holder: Processing 9x12.

So here's another answer: a 3D printed adapter kit:

Now we could have the parts printed for you but that would be way more hassle than we think it's worth. Just shipping the parts overseas, (90% of the 9x12 market is in Europe), would cost more than the parts. Besides, everyone has a 3D printer, or knows someone who does.

So just download the files here: 9x12 Adapter Kit and print your own.

Some comments, notes and disclaimers:

• These are STL files and intended for use on an SLA printer.
• Print in the resin of your choice and super glue them in place.
• You'll need to print two of each part to convert one film holder.
• Note that there is a left rail, right rail and bottom stop.
• Standard disclaimers apply, use at your own risk. Stearman Press is not responsible for anything involving these files etc.
• We cannot provide guidance regarding 3D printer settings, materials etc.
• Not for resale but you are allowed pay someone to print them for you. Note that there are numerous services online that offer 3D parts.
• Obviously, the film holder isn't included.
• Be sure to check the fit carefully before applying glue.
• Some filing, sanding or other adjustment might be required to ensure a proper fit.

Excellent, though I got excited at first thinking you were talking about Imperial measurements—there are quite a few Vageeswari 10x12’s out there (as well as bespoke Canhams)—it would be nice to get a “Layton mod“ of the 810 on the
long axis for that native format.

Thanks ! I'm using a 3D printed one, found on Thingiverse. Thanks for sharing, will look to get someone print the kit for me.

Good on you!

Agreed!

I didn't think the modification of the Rev. 1 holder would work on the newer sheet film holders in a SP-445, so this info was welcome.

I assume I can glue these rails to both sides of one adapter and if I modified two of them I could do a total of 4 sheets in my SP-445.

Yes, four sheets in the SP-445 and six in the soon to be available SP-645.
