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.
smart!
the only thing I'd worry about is 3d prints not being actually sealed. the layer lines are never airtight and always allow air and thus moisture to leak past them unless a lacquer sealant is applied. so this won't keep film very fresh for a very long time but would work great for travel and transport!
Yeah it's definitely not for long term storage, it's primarily for something to put the film in after it's been exposed before I can get it developed and added protection during shipping.
Ideally they spend less than a month in the tubes before getting developed though.
Fun little fact about 120 film: it's just paper on the outside of roll between the film and the outside world. It basically has an IP rating of "lol" after it's been taken out of the foil.
I'm planning on making some more 120 film accessories as I dive more into it, because it's kinda niche and I'd love to make the accessories for it have a lower barrier of entry.
What it looks like closed for those curious.
I guess empty ones are hard to find - but some manufacturers (like Foma) are selling their films in them. In other news, I'm drowning in those things.
I didn't know some manufacturers do that, that's pretty cool
I wish more would do that lol

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.
