Analog film scan device for (D)SLR

Holding frames to convert analog film media with a (D)SLR

Get your beloved media to the digital age.

Stuff you need:

• SLR
• Macro lens
• Flash (recommended)

These parts are optimized to get the highest possible conversion quality. The lens adapter is designed for the Sony EF 90mm macro lens. This part is individual to this setup, the rest is always the same. If you use another lens the dia_hood4sony90mmmacro.stl needs to be replaces with your own design.

Three mounts are included:

• negative film
• slide Agfa old style
• slide Agfa CS

Assembly process for the negative mount is documented on youtube: https://youtu.be/3BPvGk3-Or8

BOM, or what you need to bring:

• 4-8 DIN912 M3 8mm screws each
• 4-8 DIN562 M3 nuts
• 4 bearing 695 for the negative mount
• 1 GT2 belt closed loop 200mm
• Steel rod 5mm for the axle

You will be rewarded with insane conversion quality. Happy "scanning"

Print instructions

PETG highly recommended.

For positive mount Agfa you need to print:
1x dia_holdingrfame_agfa.stl
1x dia_hoodmount.stl

For positive mount Agfa CS you need to print:
1x dia_holdingrfame_agfacs.stl
1x dia_hoodmount.stl

for negeative scan mount you need to print:
1x nagative_frontcover.stl
1x negative_5mmknob.stl
1x nagative_mainbody.stl
1x nagative_backtube.stl
2x negative_gears.stl (print only one at a time)

To attach these to a lens you need a lens adapter which may be connected to each of the scan mounts.
If you use the 90mm Macro EF lens from sony it is this file:
1x dia_hood4sony90mmmacro.stl

If you intend to use another lens you need to build your own adapter. I created a generic lens hood designer for Sony lenses to be found here:

If you created one let me know, I would add it here to share.

Update

2022-01-28: added a second version of the negative axle if to of the same don't fit. See comment. 

2022-02-14 The axles are not print easily , however print quality can be improved a lot if you print one axle at a time only. There is an 3mf file attached or see the gcode file.
