I came across this in a recent computer-related publication, oddly enough. It is intended for 4x5 cyanotypes, though I see no reason other materials could not be used, and I think it might accept roll-film too. It is a split back design, which is nice.
The source file has the option to rescale the design, provided the 3D printer can handle the objects. It is written in FreeCAD Python. I have not tried printing it yet - though at first glance it seems to have potential. I think the Python code is a slightly different version from the included STL files. Anyway, might be worth a look.
