Unfinished and untested model of 120/220 developing tank
The price of the print was estimated on 300 euro, so I gave up on it. According to the printers the screwing mechanism isnt optimised for 3d plastic printing and the whole thing is untested.
The spools should be able to take both 120 and 220 films. My idea was to load one film from the inside and one from the outside so I could have two 120 films on one spool.
The black part is a light trap based on a Penrose's unilluminable room. I have tested it with blender for light leaks and it should be light proof while allowing liquids to pass.
From materials you should pick something resistant to acidic and alkalic substances.
In the STL I included files scaled by a factor of 1000, because sometimes the exports are funky.
