My guess it that the failure point was the winder shaft. I suspect that realistically, you would have to make that from steel as abs plastic is not robust enough.

Its a neat idea though, but probably requires a little more engineering to get it right.

Where did you get the design?

The failure point was in fact the barrel height, the winder shaft is surprisingly strong, pla, in this case, snaps rather than bends under stress.

The height was too high for the Seiko spring allowing coils to jump over another, combine that with the fact it had been abused a little with a couple of kinks I straightened. It snapped off at the saddle.

The file was from thingiverse. I don't have the link handy though.

Interesting. If the CAD file is in the files on thingiverse, then you could presumably adjust the height of the barrel so it may be possible to fix the issue. I may take a look at this when I get some spare time. If you have the link, that might save me a git of google time.

Came to me hiding amongst lots of stuff in a repairman estate, never used it.

There's an scad file in there if that's useful?

This tool does look completely useless:) but, it is a tool however.

I have a vintage Rocket crystal tool with base in the box from ebay, Got it for under $10.00 and use it all the time.
