One way spring A.R.S.H. (Auto-Rewind Spool Holder) – Lò xo 1 chiều

Made this remix due to the original springs, did not last long, as well as it caused problems that the spring could not keep the filament tight due to the "short" return.
Two different springs have been made, one running right and one running left.
They come as MMU print and without.
I uploaded a standard fusion 360 file.

NB. When slicing it in PrusaSlicer it will take a while to complete, give it time, can bring most PCs to their knees.
