Hasselblad Film Magazine Mount
A Hasselblad mount for your old C12/C16 film magazine. The lens board is replaceable and parts are easily changed if they are worn out.
Lensholder for a pinhole, Holga lens and a Pentax 6x7 mount is provided, including a matte screen if you want to a more critical composion.
Material needed
Note: The parts need to be printed on a calibrated printer in order to get the best fit. Also be aware that filament particles can affect the performance of your film magazine.
About the printed parts
| Print all the parts, no support is required. The pinhole/capsule part should be cut in PrusaSlicer at 5 mm, rotate the lower part. Sandpaper the cut surfaces and glue them together with Loctite. | ||
| The hassymountdiy.stl may serve as a starting point for making your own lens cone. | ||
| Lensboard: Sandpaper the surfaces and glue them together with Loctite. | ||
| Two variants of the film magazine frame is available, I recommend the green one since it will shield the film better from any light leaks. | ||
| I buy my pinholes from https://realitysosubtle.fr/buy-pinholes/. They are mounted on thin 20mm discs. Mount them without glue. Paint the upper part matte black. | ||
| The decoration shim is optional, depending on the screws you are using. | |
| The Pentax 67 mount is made for the helicoid extension tube in mind. |
Assembly
The Hasselblad mount is assembled by using the M3x30 screws:
The red part need to be adjusted to get a proper fit to the film magazine. Insert nuts in the slots and add the M3x10 screws - do not tighten them. Assemble the other parts and tighten them with the M3x30 screws. Insert the hooks (red part below), attach the film magazine, adjust the fit and tighten the hooks by the M3x10 screws.
Add your desired lens board. If you're using a lens, you may try out the matte screen holder:
First light: Using the matte screen and Angulon 65mm - No light leaks!
If you are using the 0.3 mm pinhole, the aperture is f=167 according to https://www.mrpinhole.com/calcpinh.php :
