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!
