Rewinder Shaft - JV Remix

I was having some issues with assembly, as Mark's version of the rewinder shaft allowed the spring to move too much for my clumsy hands.  It would pop out, or slide around, and generally made it difficult for me to easily assemble.  

I had also noticed that others had some issues similar to me, in that the original shaft would slip out of the uprights due to not having enough length.  While it's nice and flush with the uprights, I really didn't want to worry about whether a spool would come loose, or cocked, during a print.

There are at least 3 other designs at the time I'm publishing this, but none of them seemed to hit the sweet spot I was looking for (I printed ALL of them), so I remixed Mark's.  Also, I noticed that during assembly, none seem to be as smooth as the one @GunplaMark has here, but even his was a bit of an effort for some of the pieces when I assembled the rewinder.  If you find that you'd prefer a longer bit poking out the sides than mine, the other models DO seem to work, in my own testing.  There's enough versions so far that the choice is really up to you for what you'd like.

In trying to fix the slot to a thinner width, it quickly became apparent that I would have a bugger of a time adapting it, so I just ended up rebuilding the whole shaft.  I figured while I was at it, I would smooth out the whole thing.  I've found mine fits the uprights nicely, the bearings slide on with a little less friction than Mark's, while still seeming to have sufficient grab, and the C-clips Mark has included worked perfectly with this remix, zero fitment issues with any of his stock parts.

I also shortened the slot, as a good chunk of it is hidden during assembly by the slip disc and the cover.  This helped with the spring sliding side-to-side on me, and the slot is still relatively easy to slip the spring into (TWSS).  Everything seems to stay put a lot better, and makes assembly a bit easier for me.  Hope you find it as useful as it's been for me.
