I needed some film canisters for 120 film and turns out they're actually hard to find.
And when I did find models for them they had super thin caps so I decided to model one up with a better (IMO) method for securing the cap than threads.
Here's a link for those that want to check it out.
I also made a version for 116 film that's also in the link above.
Also if anyone has a roll of 220 film they could snag the dims of for me that would be great.
In the early days, all those types of film were sold in injection moulded clip on cap tube canisters.
But I shouldn't be surprised that the small sales market today. Means no one is running a big factory selling the canisters. I only ever used 32mm. My brother did a little with larger format films, so I can ask if he has any canisters in the attic. If that helped at all. (measurement and design wise) Not sure what other help I can offer. But if you think of anything a guy from the times film was common can offer. Feel free.
