lathe spindle respooler

I made this spool holder to be able to respool on my wood lathe. It works great after a few revisions. the 70% infill may be overkill but I felt it was best after breaking the bolt threads off on the first attempt. I would not use this on a lathe without a VFD, I got up to around 90 RPM once I got comfortable with it, but I doubt its going to work well once you get above 120. Lathe must run in forward, filament going underneath, or the unit will unthread from the spindle nose.I have also added a 1"X8TPI (I hav e a 1.25X8 lathe so I couldn't check the spindle threads) model and the base fusion files if anyone wants to tinker with it.
