Mask/Holder for 4x5" sheet film

[daliborwalk]

Hello, you can find the info for the 3D printed 4x5! sheet film holder for scanning/enlarging with no glass tables(there is also info in English on that webpage):

Mask(a) 4x5" - Analog Prints

(English info listed below)Maska/držák plochého filmu rozměru 4×5 palců – umožňuje skenovat, či zvětšovat bez skel a přitom je film držen v rovině. Vyrobeno pomocí 3D tisku, potřebujete 2 kusy, které spojíte k sobě. Soubor pro 3D tiskárnu: https://www.thingiverse.com/thing:4524691 Testováno a...

Nice. I made something similar recently:

It's a 2-piece design like yours, but with a hinged lid. I included a recess for a little cylindrical magnet in the baseplate and a metal plate in the lid so that it snaps shut. For the hinges I generally melt plain iron nails (1.8mm diameter) through the hinge holes.

Since sheet film is quite stiff, it sort of works OK but for critical sharpness and big enlargements the sag can be a problem. A tensioning system or a glass carrier is preferable for those. These 3D printing thingies work in a pinch and for non-critical stuff.

Hi both, I know this is a rather old thread but I cannot find any options online for 3d printable scan holders for large format. I was wondering if you could share your project files in stl or even better cad?

Thank you so much in advantage

I used it for a year or two; it worked OK but wasn't as solid as a factory made film holder. It did the job, though. Note that it's glassless, so your negatives may sag, depending on what film you use.
