3D Printing Minox Cassettes: Fail

A few attempts and the camera I’m trying to use

I’ve been trying to print Minox film cassettes for a while now with no success. I love the Minox system for its tinyness and amazing design, not to mention the nice pictures you can get with it. But I’ve only got a few film cassettes and I’m too mean to buy any more. So I thought I’d print some with my lovely new printer. It kind of works. The finished articles are almost useable. But not quite. Even if I use the high resolution 0.2mm nozzle. The problem is that some of the sides of the cassette lids are just one strand of filament wide. The printer can print these just fine, but they haven’t got enough strength to stay attached to the lid for very long, as you can see above.

I’d be happy to trace printability for film length: in other words a 24 shot exposure film held in a cassette that has double thick walls would be just fine with me. Unfortunately I’ve not found a way to tweak the design just yet. If anyone reading this can point me at designs I can work with I’d love to have another go.
