Fixing the achilles heel of the Leica CL / Leitz Minolta CL - with a brand new, 3D printed take up s

Hi everyone, sorry if you keep seeing this - I've posted it to many other forums.

 

I'm currently working on a project to once and for all fix the analogue Leica CL's broken take up spool problem, by 3D printing them.

 

I've ran a roll through mine with version 2 of the spool and it works pretty good, but i'm working on version 3 which should be better still - I got the dimensions slightly wrong on this one - it's too short.

 

How many of you CL owners would be interested in buying such an item? They'd cost around £20 and be sold through eBay all said and done, and I'd make a video showing how to take apart the CL and install them, as well as reassembly - International shipping would happen too through the eBay GSP as I'm UK based.

 

The attached photo is version 2 and not by any means the final version as this is still in very early development, but the quality of the ones that go on sale will be much higher. This one was printed by a friend of mine, but I'm soon going to acquire my own printer and make them much better.

 

I know also that this doesn't look anything like the original, but when I copied the original part dimension for dimension, curve by curve, it didn't work and suffered the same problems as the original.. immediately. Thus I simplified it and made it more "3D Printer friendly."

 

Thanks

 

Tom

 

It's quite an interesting age with 3d printing able to make this sort of thing. My watchmaker is making a removal tool for my watch.

What are you using for feed material?

What's the coupling like into the camera's wind-on mechanism? Because I'm thinking it might be quicker and easier to cut slots in a ready-made 35mm feed spool.
