Minox Film Cutter by stenokit

This three-part device enables you to slit a 35mm film in pieces that can be put in an empty Minox cartridge.
This process needs to be done in the dark.
I remixed the Minox Filmcutter V2 from cpmalek https://www.thingiverse.com/cpmalek/designs

The ‘Blade’ piece holds three double-sided razor blades
The ‘Box’ piece covers the bottom of the blades and avoids injury
The ‘Cover’ piece keeps the film in place during the cutting process
Changes :
I removed the clips of the ‘Box’ (on my PLA model they broke at the first use). I don't need them, the ‘Box’ stays in place with the natural friction.
I reduced the height of the ’Blade’ piece so that the blades stick out on both sides and thus can be adjusted when they are put in place. The box prevents any possible injury on the bottom of the device once the blades are secured in place.
I reduced the height of the ‘Box’ (it prints a little quicker !). It is anyway big enough to accommodate normal double-sided razor blades.
I created two finishes on each side of the ‘Blade’ piece and of the ‘Box’. Rounded and sharp. Thus, in the dark you can tell which side is which (in my case : rounded is the side where the 35 mm film is fed).
I created the necessary cuts in order to use the nuts I had in my toolbox (large flat head). So it should now work for any type of M5 x 30 bolt.
Printing :
The ‘Blade’ piece needs supports. I tested 'line' supports and they where easy to remove. The piece must be placed with the four angle tabs facing up.
The two other pieces don't need support : the bottom of the ‘Box’ should be facing down and the top of the ‘Cover’ should be facing down.
On my 3D printer the ‘Blade’ piece took 3 hours to print (0.2mm layers, 20% infill) and the combined ‘Box’ and ‘Cover’ took also 3 hours (same settings).
